If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.
Answers
Answer:
The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!
The law of sins says: a/SinA = b/SinB = c/sinC
For this to be an isosceles triangle then side a must equal side c
so then a/sinA = c/sinC
Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.

What are the domain and range of g ( x ) =
-1/4( x - 17)2 + 61?
Answers
Answer:
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Step-by-step explanation:
Step-by-step explanation:
step 1. I assume g(x) = -(1/4)(x - 17)^2 + 61
step 2. domain is all the possible x's. all x's are permissible
step 3. domain: "all x" written as ( inf, -inf )
step 4. range is all the possible y values. g(x) is a quadratic pointing downward. the vertex (17,61) is the highest included y value
step 5. range: [61, -inf).

Need to find x, and measure of angle DEF
Answers
Answer:
x = 5
[tex] m\angle DEF = 90\degree [/tex]
Step-by-step explanation:
GE is the angle bisector of quadrilateral DEFG,
Thus, by angle bisector property:
9x°= (5x + 20)°
9x = 5x + 20
9x - 5x = 20
4x = 20
x = 20/4
x = 5
[tex] m\angle DEF = 9x\degree + (5x+20)\degree [/tex]
[tex] m\angle DEF = (14x+20)\degree [/tex]
[tex] m\angle DEF = (14\times 5+20)\degree [/tex]
[tex] m\angle DEF = (70+20)\degree [/tex]
[tex] m\angle DEF = 90\degree [/tex]
pls help me !! will mark brainliest... i just need you to solve for m<1 and m<7 !! thanks !!
Answers
Step-by-step explanation:
=( n-2)180
= ( 4 - 2 )180
= 360
So, 144 + 90 + m<2 +m<1 = 360
144 + 90 + 85 + m<1 = 360
319 + m<1 = 360
m<1 = 360 - 319
m<1 = 41
their is an unknown angle so let's call it x
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106

12.75ft²
Step-by-step explanation:
Step 1: Determine the formula for the area of a trapezoid
The formula for the area of a trapezoid is A=1/2(b1+b2)*h where b1 and b2 are the bases of the trapezoid and h is the height of the trapezoid.
Step 2: List given information
b1=8ft
b2=9ft
h=1.5ft
Step 3: Plug given variables into the formula
A=1/2(b1+b2)*h
A=1/2(8+9)*1.5
A=1/2(17)*1.5
A=8.5*1.5
A=12.75
So the area of the seat is 12.75ft²

non-linear function that decreases then increases
D
non-linear function that increases then decreases
Answers
Answer:
D
Step-by-step explanation:
I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.
