Answer:
As you may know, the addition of all the interior angles of a triangle always adds up to 180°.
So if we know two angles of the triangle, A1, and A2, we can find the third angle as:
A1 + A2 + X = 180°
X = 180° - A1 - A2.
Se with only knowing two angles, we can find the third angle.
So aaa is a criteria equivalent to aa.
Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.
Determine the value of z in the figure answers: z = 40° z = 90° z = 20° z = 45°
Answer:
20 degreesStep-by-step explanation:
This is a linear pair, whose sum always equals 180 degrees,
hence, we can set up the equation:
2z+140=180
2z=180-140
2z=40
z=40/2
z=20
Thus, the answer is 20 degrees
Answer:
z = 20°
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
2z+ 140 = 180
Subtract 140 from each side
2z+140-140 = 180-140
2z = 40
Divide by 2
2z/2 = 40/2
z = 20

A ship is sailing due west …
Plz answer !!
Answer:
8.75° south of west
26.3 mph
Step-by-step explanation:
Let's say that east is +x and north is +y.
The sailor's horizontal velocity is -26 mph. The vertical velocity is -4 mph. So the velocity vector is in the 3rd quadrant. The direction is:
θ = tan⁻¹(-4 / -26)
θ = 188.75°, or 8.75° south of west.
The magnitude of the speed is:
v = √((-4)² + (-26)²)
v = 26.3 mph

Select all true statements
Answer:
f(x) has a larger growth rate
f(x) is always greater than g(x)
Step-by-step explanation:
f(x) = 2/5 x
g(x) = -2x
the slope of f(x) when graphed is 2/5 x, which is a positive value making it a larger growth rate than g(x) and it also will always be greater since the value of f(x) is positive
therefore the correct true statements are:
f(x) has a larger growth rate, and f(x) is always greater than g(x)
options 1 and 3
Step-by-step explanation:
option 1 is correct because f (x) is positive hence making it greater than g(x) which is negative.

Step-by-step explanation:
Angles: 45°: 45°: 90°
Ratio of sides: 1:1:√2
Given c= 55
a =c/√2
a=55/√2 = 38.9
b=a+2 = 38.9+2 =41.9
The length of the legs of the triangle is 41.9
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.
Angles are: 45°: 45°: 90°
The ratio of sides: 1:1:√2
Given c = 55
a = c/√2
a = 55/√2
a = 38.9
b = a+2
b = 38.9+2
b =41.9

There are 1250 students in a school. 58% of them are female. How many are male?
Answer:525 boys
Step-by-step explanation:
Multiply 1250 times .58 and then subtract that answer from 1250....
1250x.58=725
1250-725=525
Answer:
There are 525 boys in that school.
Step-by-step explanation:
Since the number of students in that school are 1250 and 58% of them are female, therefore the percentage of the male is
⇒100% - 58% = 42%
To find how many boys are in that school, you multiply 1250 by 42%.
i.e. [tex]\frac{42}{100} * 1250[/tex]
= [tex]\frac{42}{10} * 125[/tex]
= 4.2 × 125
= 525
∴ There are 525 boys in that school.
OR
You can find the number of boys there by subtract the product of 58% and 1250 by 1250.
i.e. Number of girls= [tex]\frac{58}{100} * 1250[/tex]
= [tex]\frac{58}{10} * 125[/tex]
= 5.8 × 125
= 725
∴ The boys in that school are:
= 1250 - 725
= 525
∴ There are 525 boys in that school.
