the measure of one angle of a triangle is 105 what do you know about the measure of the other two angles?
Answer:
they add up to 75 degrees
Step-by-step explanation:
the interior angles of a triangle always have to total to 180 degrees, so if one of them is 105 the other two are 180 - 105 = 75 degrees
Answer:
Each angle could possibly be 37.5
Step-by-step explanation:
the sum of all the angles inside a triangle is 180 degrees. If one angle is 105, then we take 105 from 180
180 - 105 = 75
75 is the measure of all the missing angles. since there are two missing angles, we can divide 75 by two for the two angles
75 divided by two is 37.5

HELP AND WILL GIVE BRAINLIEST!!! Solve for x
Answer:
let the opposite angle of 43=y
57°+43°+y=180°[by sum of all angle is 180°]
100+y=180°
y=180°-100
y=80°
opposite angle of x is equal to the 80°
so the equation will be like this
x+x+80°=180°
2x+80°=180°
2x=180°-80°
2x=100
x=100/2
x=50°
so the value of x is 50°

how many degrees is a 12-gon
Answer:
150 degrees
Step-by-step explanation:
The degrees of a n-sided polygon is given by the expression:
180 ( n − 2 )
where n is the number of sides. As we know that it ahs 12 sides, so
=180 ( 12 − 2 )
=180 ( 10 )
=1800 i.e. Therefore, there are 1800 degrees in a 12
-gon.
To find the measure of the angles, we know that the sum of all the angles is 1800 degrees, and there are 12 angles. So,
1800/12 = 150
So, the measure of the interior angle of a 12-gon is 150 degrees.

30 POINTS!!!!! What is the domain for each function below?
Picture included below!
-For the 1st equation, the options are the greater than/equal to symbol and the less than/equal to symbol, and then 3, -3, and 0.
-For the 2nd equation, the options are the greater than/equal to symbol and the less than/equal to symbol, and 0 and 3.
The domain is the set of input values for which the function is real and defined.
Find non negative values for the radicals.
For y = sqrt(3-x) if x is greater than the 3 the value under the square root would be negative which would result in a non real number.
The answer needs to be x <= 3 ( less than or equal to)
For y = sqrt(3x), if x is less than 0, the number under the sqrt root would be negative resulting in a non real number.
The answer is x >= 0 ( greater than or equal to)
The bakers at Healthy Bakery can make 340 bagels in 10 hours . How many bagels can they bake in 24 hours ? What was that rate per hour ?
PLEASE HELP ME
Answer: 816
Step-by-step explanation:340+340=680 in 20 hours and 340 divided by 10=34/hour so 34x4=136
So.., 680+136=816
What is an
equation of the line that passes through the points (0, -2)
and (6, 6)?
Answer:
8/6x+2................
Answer: y=(4/3)x-2
Step-by-step explanation:
(y-y1)/(x-x1)=(y2-y1)/(x2-x1)
x1=0, x2=6
y1=-2, y2=6
(y-(-2))/(x-0)=(6-(-2))/(6-0)
(y+2)/(x)=(6+2)/6
(y+2)/(x)=8/6=4/3
Cross multiply
3(y+2)=4x
y+2=(4/3)x
y=(4/3)x-2
What is the value of X
Answer:
The Value of X in 2nd one can be 14√3.
The Value of X in 1st one can be 6√3.
Step-by-step explanation:
2.)here we used tan 60° formula with P/B as x/14 respectively.
as the value of tan 60° is √3, we got,
√3= x/14
x= 14√3.
1.) Here we used sin 30° formula with 1/√2 as P/H
so we got,
6/x= 1/√2
hence the answer comes:-
x= 6√2..

Solve for x in the following figure
Answer:
x = 80
Step-by-step explanation:
∡KJL = 180 - (60 + 40)
∡KJL = 80
∡XJK + ∡KJL = 180 (they are a linear pair of angles)
x + 20 + 80 = 180
x + 100 = 180
x = 80

solve for x,x(3+9)=72
Answer:
x(3+9)=72
or, x(12)=72
or, x=72÷12
or, x = 6 ans.
Answer: x=6
Step-by-step explanation:
Let's solve your equation step-by-step.
x(3+9)=72
Step 1: Simplify both sides of the equation.
12x=72
Step 2: Divide both sides by 12.
12x/12=72/12
x=6

An arithmetic sequence has second term 28 and the fifth term 52. (3 marks) a. Find u1 and d. b. Find u10
Answer: See explanation
Step-by-step explanation:
Second term = a + d = 28 ....... i
Fifth term = a + 4d = 52 ......... ii
Subtract equation I from ii
3d = 24
d = 24/3 = 8
d = common difference = 8
Since a + d = 28
a + 8 = 28
a = 28 - 8 = 20
First term = a = 20
u10 = a + (n-1)d
= a + (10-1)8
= 20 + (9 × 8)
= 20 + 72
= 92
