Answer:
12
Step-by-step explanation:
Assume that those angles' curve in the triangle have same measure.
Law of Sin states that:
From the question, assume that B and C are congruent or have same measure. Let B and C be congruent; angle B = angle C thus:-
Let b = x and c = 12; for angle B, it's not given so leave it.
Multiply both sides by LCM which is 12x.
Divide both sides by sinB.
Therefore, x = 12.
Answer:
50
Step-by-step explanation:
2/5x+10=30
2/5x= 30-10
2/5x= 20
2x= 20*5
2x= 100
x= 100/2
x= 50
Answer:
w = 13
Step-by-step explanation:
Right angle: 90°
Write an equation:
(4w + 5)° + 33° = 90°
Solve for w.
(4w + 5)° = 90° - 33°
(4w + 5)° = 57°
You can take away the brackets.
4w + 5 = 57
Isolate w.
4w = 57 - 5
4w = 52
w = 52 ÷ 4
w = 13
