Answer 2

Explicación paso a paso:

• 10)

5X + 3X + 2 = 180

8X = 178

X = 178/8 = 22.25

reemplazamos...

5X = 5 × 22.25 = 111.25

3X + 2 = 3 × 22.25 + 2 = 68.75

• 11)

X – 3 + 2X + 10 = 180

3X = 180 – 7

3X = 173

X = 173/3 = 57.66

reemplazamos....

X – 3 = 57.66 – 3 = 54.68

2X + 10 = 2 × 57.66 + 10 = 125.32

• 12)

5X + X = 90

6X = 90

X = 90/6 = 15

reemplazamos..

5X = 5 × 15 = 75

X = 15

• 13)

2X + 5 + X – 4 = 180

3X + 1 = 180

3X = 179

X = 179/3 = 59.7

reemplazamos....

2X + 5 = 2 × 59.6 + 5 = 124.4

X – 4 = 59.6 — 4 = 55.6

• 14)

A = 130°

B = 50°

C = 50°

D = 130°

E = 50°

F = 130°

G = 50°

H = 130°

• 15)

A = X = 45°

B = 135°

C = 135°

D = 45°

E = 3X = 3 × 45° = 135°

F = 45°

G = 135°

H = 45°

A = X ; A = H por lo tanto, H = X

3X + X = 180

4X = 180

X = 180/4 = 45

X = 45°

• 16)

A = 3X + 4 = 3 × 36.2 + 4 = 112.6°

B = 67.4°

C = 2X – 5 = 2 × 36.2 – 5 = 67.4°

D = 112.6°

E = 67.4°

F = 112.6°

G = 67.4°

H = 112.6°

3X + 4 + 2X – 5 = 180

5X – 1 = 180

5X = 181

X = 181 / 5 = 36.2

• 17)

A = 163.65°

B = 16.35°

C = 16.35°

D = 163.65°

E = 163.65°

F = 16.35°

G = 163.65°

H = 16.35°
