Question

Urgent!!! I need help with all of these problems!!!

Answer 1

Answer:

3. m∠1 = 92; m∠2 = 24; m∠3 = 64; m∠4 = 35; m∠5 = 8

4. m∠1 = 35; m∠2 = 65; m∠3 = 29; m∠4 = 115; m∠5 = 65; m∠6= 36; m∠7 = 144

5. x = 13

6. x = 36

Step-by-step explanation:

3. 88 + m∠1 = 180

m∠1 = 92

m∠3 = 64

m∠1 + m∠2 + m∠3 = 180

92 + m∠2 + 64 = 180

m∠2 = 24

64 + 81 + m∠4 = 180

m∠4 = 35

64 + 81 = 64 + m∠5

81 = m∠5

4.

m∠4 = 115

m∠2 = m∠5

m∠2 = 65

m∠5 = 65

65 + 61 + 90 + m∠7 = 360

m∠7 = 144

m∠6 = 36

m∠3 + 36 + 115 = 180

m∠3 = 29

m∠1 + 65 + 80 = 180

m∠1 = 35

5. 8x - 35 + 3x - 1 + 6x - 5 = 180

17x - 41 = 180

17x  = 221

x = 13

5x - 11 + 2x + 20 = 11x - 63

7x + 9 = 11x - 63

-2x = -72

x = 36

Answer 2

4. m1= 35

m2= 65

m3= 29

m4=115

m5=65

m6=36

m7=144

Those are the angles for question 4, i didnt know how to make the sign and Im not going to show work since that would take too long.
