Answer:
d. m∠Q = 75 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180°. This triangle is marked to show it is an isosceles triangle, so the two base angles have the same measure.
∠P +∠Q +∠R = 180°
x° +(2x +15)° +(2x +15)° = 180°
5x = 150 . . . . . . . . . . . . . . . . . . . divide by °, subtract 30
x = 30 . . . . . . . . . . . . . . . . divide by 5
m∠Q = (2x +15)° = (2(30) +15)°
m∠Q = 75°
I believe it would be 144 :)
Answer:
-4^4(4^7), in that case, the answer would be (B) -4^11
Step-by-step explanation:
Hope this helps
Step-by-step explanation:
m=-2
m^2+9m+3
substitute-2 in m
-2^2+9(-2)+3
= -19
