Answer:
42°
Step-by-step explanation:
angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°
Answer:
x = 38°
Step-by-step explanation:
in the given question,
the two angles are complementary, because sum of their measures = 90°
so,
=》52° + x = 90°
=》x = 90° - 52°
=》x = 38°

Step-by-step explanation:
First you have to organize your information:
3 Teach.= 70 children
There are 14700 children 210 times 70.
You multiply 3*210 =70*210 because if you multiple one side you have to do the other to.
This equals 630= 14700. They need 630 teachers.
They have 612 so you only have to subtract 630 -612 =18
They need 18 teachers more.
Eagle starts at 42 ft. 42+144 since it raised 144, which is 186. Then it flew down 126 ft, so subtract 126 from 186. That is 60. The eagle then raises another 25 ft. So add 60+25. Now you're at 85 ft. And then subtract the last six feet after that.
Your answer is 79 ft. Hope this helped!
