Answer:
The answer to your question is x = 3
Step-by-step explanation:
Data
m∠2 = 10x + 10
exterior angle = 110°
x = ?
Process
1.- Find the measure of the angle supplementary to the angle 110°. It will be angle y.
180° = 110° + y
- Solve for y
y = 180 - 110
y = 70
2.- From the picture we conclude that the triangle is Isosceles because two of its sides measure the same.
In an Isosceles triangle two of its angles measure the same so,
180° = 70° + 70° + ∠2
- Solve for ∠2
∠2 = 180 - 70 - 70
∠2 = 40
3.- Find x
10x + 10 = 40
Solve for x
10x = 40 - 10
10x = 30
x = 30/10
x = 3
Answer:correct answers are:
A.m<JPX=90°
B.XY & JK form right angles
E. JP=KP
F.XY⊥JK
Step-by-step explanation:
hope this helps
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!
Answer: D and A
Step-by-step explanation:
Just took the apex quiz and it’s right
An=Asub1(r)n-¹
=5(-2)7-¹
=5(64)
A7=320
