Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The ratio of girls to students is choice c, 34:72 because it said girls to students. We already know the total number of students and the number of boys, all we have to do now is subtract the total number of students to the number of boys to get the number of girls, 72 - 38 = 34......and that's it we put the number of girls then the number of students.
Answer:
68°
Step-by-step explanation:
Attached is an image of the isosceles triangle theorem.
Utilizing this theorem, we know that the bottom two angles are congruent, or the same.
We also know that there are 180° in a triangle. Lets find x!
1) Write an equation to find angle x:
56+56+x=180
2) Simplify
112+x=180
3) Subtract 112 from both sides:
x=68°
