Find all the missing sides and angles of this triangle.
3241004551 [841]

Answer:

A = 20°

AC = 6.6

BC = 2.4

Step-by-step explanation:

Given:

B = 70°

C = right angle = 90°

AB = 7

Required:

A, AC, and BC

Solution:

✔️A = 180 - (90 + 70) (sum of triangle)

A = 20°

✔️Use trigonometric function to find AC:

Refernce angle = 70°

Opp = AC

Hypotenuse = 7

Apply SOH,

sin 70 = Opp/Hyp

sin 70 = AC/7

7 * sin 70 = AC

6.57784835 = AC

AC = 6.6 (nearest tenth)

✔️Use trigonometric function to find Bc:

Refernce angle = 70°

Adj = BC

Hypotenuse = 7

Apply CAH,

cos 70 = Adj/Hyp

cos 70 = BC/7

7 * cos 70 = BC

2.394141 = BC

BC = 2.4 (nearest tenth)

18.4 + 8w = 6 (9w - 4.6)
svp [43]

Answer:


Step-by-step explanation:

18.4 + 8w = 6(-4.6 + 9w)

18.4 + 8w = (-4.6 * 6 + 9w * 6)

18.4 + 8w = (-27.6 + 54w)

18.4 + 8w + -54w = -27.6 + 54w + -54w

18.4 + -46w = -27.6 + 54w + -54w

18.4 + -18.4 + -46w = -27.6 + -18.4


Combine like terms: 18.4 + -18.4 = 0.0

0.0 + -46w = -27.6 + -18.4

-46w = -27.6 + -18.4

-27.6 + -18.4 = -46

-46w = -46


w = 1


Simplifying

w = 1
