How do I solve these two?

1.D

2.B

Step-by-step explanation:

For the first one divide see which one is less which is D

For the second one Ive always used the method kcf keep change flip so you keep the change ÷ to multiplication so then flip so the equation would be

x so multiply the 15 by 9 then you get 135 then divide by 2 so thats your answer

answer:  

step-by-step explanation:

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
