Answer:
B. 39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
(3x +1) +(11x -4) +(5x -7) = 180
19x -10 = 180 . . . . . collect terms
19x = 190 . . . . . . . . add 10
x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
- 3·10 +1 = 31
- 11·10 -4 = 106
- 5·10 -7 = 43
The appropriate choice is ...
B. 31°, 106°, 43°

Answer:
a. 28
Step-by-step explanation:
Given:

We need to evaluate given expression to find the value of 'h'.
Solution:

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

Now we will use Division property of equality and divide both side by 2.95 we get;

Hence After evaluating given expression we get the value of 'h' as 28.
