Answer:
diagram of truss with some angles missing
What are the measures of the angles located at positions a, b, & c? Note: the figure is symmetrical on the vertical through angle b.
The large triangle is an isosceles triangle. The two angles on the base are equal. Angle a = 35°
We now know two angles in the largest triangle. The third angle, angle b must add to these to make 180°.
35° + 35° + b = 180°
b = 180° - 70°
b = 110°
We now know two angles in a quadrilateral. The two unknown angles, including angle c are equal. All four angles add up to 360°.
2c + 110° + 120° = 360°
2c = 360° - 230°
2c = 130°
c = 65°

Answer:
m > 5 or m < -19
Step-by-step explanation:
We are given the Inequality:

First, add both sides by 4.

<u>A</u><u>b</u><u>s</u><u>o</u><u>l</u><u>u</u><u>t</u><u>e</u><u> </u><u>V</u><u>a</u><u>l</u><u>u</u><u>e</u><u> </u><u>P</u><u>r</u><u>o</u><u>p</u><u>e</u><u>r</u><u>t</u><u>y</u>

Given a = any expressions and b = any positive numbers, zero or any expressions.

From the Inequality, change > to equal

Subtract 7 both sides.

±12-7 can be 12-7 = 5 or -12-7 = -19

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.
Since the absolute graph is above constant graph when x > 5 and x <-19.
Therefore,

<span>2x + 18 - 1 = 33
First combine like terms on the left side.
2x + 17 = 33
Now subtract 17 from both sides.
2x = 16
Lastly, divide both sides by 2.
x = 8
The answer is x = 8.</span>
