Answer:
3.35
Step-by-step explanation:
Can’t be shorter than the sides I don’t think and 11 is way to high
The answer is A. I like to use SohCahToa to help me out. The S would be Sin. And from there its oposite (8.5) over adjacent (x). hope this helps :)
Equation of slope: (y2-y1)/(x2-x1)
(-10 - -2) / (a - -1)
(-10 + 2) / (a + 1)
(-8) / (a + 1)
set this equal to 4 since the slope is given:
4 = -8/(a+1)
multiply (a+1) to both sides
4(a+1) = -8
distribute
4a + 4 = -8
subtract 4 from both sides
4a = -12
divide both sides by 4
a = -3
ANSWER: a = -3
Answer:44
Step-by-step explanation:the two triangles are congruent , so we deduce from that the angle B=angle E =48
So, x+4=48 , x=44 degree
