Answer:

x = 60°

Step-by-step explanation:

A triangle is equal to 180°

Make an equation and solve:

30° + 90° + x = 180°

120° + x = 180°

x = 180° - 120°

<u>x = 60°</u>

Jeanine is twice as old as her brother Marc. If<br> the sum of their ages is 24, how old is Jeanine?
Vesnalui [34]
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
