Answer 1

are you asking for the angle?

Answer 2

set up an equation, you know that the sum of 4x and 3x-8 must be 90 degrees

Answer 3

4x + 3x - 8 = 90
now solve for x...and sub that value back into 3x - 8 to find the angle CDJ

Answer 4

The figure shows three graphs of functions defined by formulas of the form y = kx. Specify for each graph corresponds to the formula it by selecting it from among


and below. 1) y = 2x 2) y = -2x 3) y = 1 / 2x 4) y = -1 / 2x

Answer 5

7x - 8 = 90
7x = 98
x = 14
now sub 14 in for x in 3x - 8 to find <CDJ

Answer 6

3(14) - 8 = mCDJ....can you do the math

Answer 7

34

Answer 8

bingo...
check...
4x + 3x - 8 = 90
4(14) + 3(14) - 8 = 90
56 + 42 - 8 = 90
98 - 8 = 90
90 = 90 (correct)

So mCDJ = 34 and mADC = 56....

Answer 9

thank you!

Answer 10

YW :)
