Answer: B
Step-by-step explanation: u have to simplify the 36 and the 12
(x-4)(x+9) is equivalent to x^2+5x-36
all you need to do is factor the equation
Sum of exterior angles of any polygon is 360 degrees.
<span>Each exterior angle of a regular polygon = 360/n where n is the number of sides. </span>
<span>So, n = 360/20 = 18. Your answer is D
Hope this helps.</span>
Six-sixths=16
Eight-tenths=8/10
Seven-ninths=7/9
Three-eights=3/8
The sum of the angles of a triangle is 180º.
We have three angles:
∠yxz=3x+5
∠xzy=180º-(8x-14)
∠xyz=4x
Therefore:
(3x+5º) + [180º-(8x-14º)]+(4x)=180º
3x-8x+4x=180º-5º-14º-180º
-x=-19º
x=19º
∠yxz=3x+5º =3(19º)+5º=62º
∠xzy=180º-(8x-14)=180º-(8(19º)-14)=42º
∠xyz=4x=4(19º)=76º
Answer: m∠yxz= 62º.
