To find out the answer, we must see how big a centimeter and milimeter is to a standard meter 1 cm = 0.01 m 1 mm = 0.001 m 12 cm = 0.12 m 98 mm = 0.098 m, 12 cm is bigger
Angle 1: 52 degrees
angle 2: 79 degrees
angle 3: 38 degrees
explanation:
angle 1: 180 - 90 - 38 = 52
angle 2: 180 - 63 - 38 = 79
angle 3: 90 - 52
6 • x + 6 • 9
I’m pretty sure this is right because you have to distribute the 6 to both of the numbers inside of the parentheses
Answer:
The missing side is 
The missing angles are
and
Step-by-step explanation:
Given



The implication of this question is to solve for the missing side and the two missing angles
Represent
Angle A with 
Angle B with 
Angle C with 
Calculating B
This will be calculated using cosine formula as thus;

Substitute values for A, C and 




Take Square root of both sides

<em>(Approximated)</em>
Calculating 
This will be calculated using cosine formula as thus;

2x+5=50
-5 -5
—————-
2x = 45
Divide by 2
45/2 = 22.5
I hope this makes sense
