What I the answer to all 3

D: 15.75

A: -14.84

C: x = 11

Step-by-step explanation:

Two negatives make a positive, do 7.2 + 8.55 and you will get 15.75. If it's easier, do -10.5 + -4.34 to get -14.84. For number three you have to distribute 1/2 to x and 1 to get 0.5x + 0.5 = -5. Subtract -0.5 on both sides to get 0.5x = 5.5. Divide 0.5 from both sides to get 11.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
