Can someone help me with this question "Given the triangle below, what is m (angle) < B, rounded to the nearest tenth?

JulsSmile [24]

The answer
the sum of the angles in a triangle is always 180°
m < B + m < A + m < C = 180°,
let's find m < B,
by applying sinus rule
14/sinB=10/sinC, so sinB= 10xsinB = 14 x sinC and therefore,
sinB=( 14/10 )sinC =7/2 sin 36° =0.82, so arcsinB=55.08°
the answer is C 55.4°

1 7/8 divided by 2 8/11

Bingel [31]

Answer: 11/16

Turn 1 7/8 into an Improper Fraction

Multiply 1×8 and get 8. Now add 7 and get 15.

1 7/8 = 15/8

Turn 2 8/11 into an Improper Fraction

Multiply 2×11 and get 22. Now add 8 and get 30.

2 8/11 = 30/11

Do Keep Change Flip

Keep: 15/8

Change ÷ into ×

Flip: 30/11 into 11/30

Your New Problem: 15/8×11/30

Multiply

15/8×11/30=165/240

Simplify

165/240÷15/15=11/16
