I Have To Turn This In Tonight Please Help class=

Sagot :

Answer:

angle a is 116 degrees

Step-by-step explanation:

ok so first we have to make everything equal to 180 because every triangle is 180 degrees so it would be written like this:

(14x + 4) + (5x - 1) + (2x + 9) = 180

Then, we solve for x and x equals 8

After this we plug 8 back into the angle so it would be written like this:

14(8) + 4

This equals 116 degrees.

Answer:

116

Step-by-step explanation:

21x + 12 = 180

-12 -12

21x = 168

÷21 = ÷21

x = 8

14 x 8 + 4

112 +4

116
