Answer:
b^8
Step-by-step explanation:
(a^m)^n=a^(m*n)
(b^4)^2=b^(4*2)=b^8
Answer:
(D) Their angle measures cannot be equal.
Step-by-step explanation:
(A) It's fine if both angles are acute.
(B) None of the angles can be a right angle.
(C) Their sum has to be 90°.
(D) Their angle measures can be equal.
Answer:
x = 69°
Step-by-step explanation:
1). JFGHI is a pentagon, every angle in a Pentagon is equal to 108°.
2). angle JIH + angle HIE = 180°; angle JIH = 108, so angle HIE = 72°.
3). angle JDI is equal to 39° and angle IEH; so angle IEH = 39°
4). Now we know 2 out of the three angles in the triangle IHE, so we can find x!
5). x + angle HIE + angle IEH = 180°
x + 72° + 39° = 180°
x = 69°
