Answer:
Step-by-step explanation:
Side c = AB can be found using the Pythagorean theorem:
c² = a² + b² = 8² +5² = 89
c = √89 ≈ 9.43
__
Angle B is the complement of angle A, so is ...
B = 90° -A = 90° -58° = 32°
c is approximately 9.43; the measure of angle B is 32°.
Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
<u>substitute for y:</u>
x + x - 55 = -21
<u>solve for x:</u>
2x = 34
x = 17
<u>solve for y:</u>
17 + y = -21
y = -38
Answer:
a^8
Step-by-step explanation:
Write equations for the given information to solve (using J for Jeanine and M for Marc):
J=2M
J+M= 24
Now substitute 2M in for J in the second equation:
2M+M=24, 3M=24, M=8
Remember that J=2M, so if M=8, J=16.
So Jeanine is 16 and Marc is 8
