The height of the pole is the vertical leg of the right triangle. The angle of depression is an exterior angle to the triangle at its upper angle. The angle of depression is complementary to the interior angle, so the measure of the interior angle is 15. The base angles are 90 and 75. Use the tangent ratio now, using the base angle of 75 and the height of the pole being 50: tan75=50/x.
Make sure your calculator is in degree mode to do this and get that x = 13.4
Answer:
you can sum the 2 equations or suppose-10y=-7x-11
then you can get it it in the other one
step by step
0.75 because 100cm = 1m so you just move the decimal to the right by 2
Question 4
4(2x +5)
What you are going to do is called the distributive property.
First you are going to multiply the 4 and the 2 and you would get 8x.
Second you are going to multiply the 4 and the 5 and you would get 20.
Answer is 8x+20.
Sorry don't know about the other following answers
Answer:
11/12
Step-by-step explanation:
Multiply 1/4 times 3/3 and 2/3 times 4/4. That gives you 3/12 + 8/12. Add that together and you get 11/12
