Find the measure of each angle (in degrees) of
d1i1m1o1n [39]

Answer:

∠A = 88°

∠B = 92°

∠C = 88°

∠D = 92°

Step-by-step explanation:

∠A + ∠B = 180°

(2x + 4) + (3x - 34) = 180

reduce:

5x - 30 = 180

5x = 210

x = 42

∠A = 2(42) + 4 = 88°

∠B = 3(42) -34 = 92°

∠C = ∠A = 88°

∠D = ∠B = 92°

Solve for k.<br> (k)4+ 3= 14<br> ​k=<br> ​
r-ruslan [8.4K]
Solving for "K" , got it! :)
I'll make it easier to solve

(k)4+3-14=?
? = 0

4(k)-11 = 0 

Take off the '0' and the addition symbol so we can add from 11 on your sides

4(k) - 11
+11   +11
---- ----
15k. 22
      ⬆ This would be your answer for k            

 4(k) = 11
÷4 ÷4
--- ----
1K ?

K = 11/4 (for fraction)
K = 2.75 (as a decimal)
