Step-by-step explanation:
This is the answer by definition.
31
since A = 1/2 b h, and the A is 279 and the height is 18, we can plug them in and solve for b.
Answer:
m<4 = 117 degrees
Step-by-step explanation:
Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.
Angles on one side of a line add to 180 degrees.
180 - 63 = 117
The answer is 119 8/14 which simplifys to 119 4/7.
