Answer:
180
Step-by-step explanation:
Each triangle shown is a right triangle, meaning the angle is 90 degrees. All triangles equal 360 degrees, and you already have 2 90 degree angles, so just subtract 180 from 360 and you get 180.
F(2x^2 +13x+15) = 16x^4 +208x^3 + 928x^2 + 1638x+990
To find the interior of Y
Y = 180 - 135
Y = 45
The interior of Z is 49 because the angles are mirrored to each other
then, to find x,
X = 180 - 45 - 49
X = 86
so your answer should be 86.
Answer:
Step-by-step explanation:
23.m∠2=x+60
as the sides are equal.
so angles are also equal.
m∠2=45
x+60=45
x=45-60=-15°
so C
24.
74+74+m∠2=180
m∠2=180-148=32°
so 3x-4=32
3x=32+4=36
x=12°
C
25.
as the three sides are equal so angle are equal.
m∠2=60
7x-10=60
7x=60+10=70
x=10
D
