A is the answer,,,,,,,,,,
Answer:
42, 138, 138
Step-by-step explanation:
the line not adjacent to the 42 degree angle is also 42 by the vertical angles theorem. Then you find the measure of the other 2 by x+42=180 so x=138.
Answer:
m<B = 28°
Step-by-step explanation:
Given:
m<A = 112°
m<C = 40°
AC = 14
Required:
Find, m<B, AB and BC.
SOLUTION:
✍️m<B = 180° - (112° + 40°) (sum of ∆)
m<B = 28°
✍️Using sine rule, find AB.
Plug in the values into the equation.
Cross multiply
Divide both sides by sin(28)
(nearest tenth)
✍️Using sine rule, find BC.
Plug in the values into the equation.
Cross multiply
Divide both sides by sin(28)
(nearest tenth)
Final answer:801600 equation: ugh hold on this will take a few mins the second step is where the variable is defined. I just cant think of the equation. my brain doesn't work like that. I got this though give me a sec
