Please help!! Two equations are given below:
m + 5 = 20
m = n - 4
What is the solution to the set of equations in the form (m, n)? (1 point)
A. (3,7)
B. (0,4)
C. (5,1)
D. (2,6)

In the diagram below, dab and dac are adjacent angles. if mdac = 25°, what is mdab in degrees? what is mbac in degrees?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

The triangle shown has a hypotenuse with a length of 13 feet. the measure of angle a is 20 degrees. and the measure of angle b is 70 degrees. which of the following is closest to the length, in feet, of line segment ac? no need to use a calculator to find the trig numbers. each function is listed below. 4.4 5 12.2 35.7
