Answer:
ratio of boys to girls= 4:7
number of girls=21
now,
M<ZHG = 11x - 1, m<ZIHZ=24°and m<IHG = 12x + 13. Find m<IHG.
1 answer:
Answer:
m<IHG=133°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m<ZHG+m<IHZ= m<IHG -----> by angle addition postulate
substitute the given values and solve for x
11x-1+24=12x+13
Combine like terms
11x+23=12x+13
Group terms that contain the same variable
12x-11x=23-13
x=10
Find the measure of angle IHG
substitute the value of x
m<IHG= 12(10)+13 =133°
