If angle 2 measures 155 degrees in the image below, what is the measurement of angle 1?

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°

| 7 + m | - 4 > 8

cestrela7 [59]

Answer:

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

$\displaystyle \large{ |7 + m| - 4 > 8}$

First, add both sides by 4.

$\displaystyle \large{ |7 + m| - 4 + 4 > 8 + 4} \\ \displaystyle \large{ |7 + m| > 12}$

<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>

$\displaystyle \large{ |a| = \sqrt{ {a}^{2} } }$

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

$\displaystyle \large{ |a| = b \longrightarrow a = \pm b}$

From the Inequality, change > to equal

$\displaystyle \large{ 7 + m = \pm12}$

Subtract 7 both sides.

$\displaystyle \large{ 7 - 7 + m = \pm12 - 7} \\ \displaystyle \large{ m = \pm12 - 7}$

±12-7 can be 12-7 = 5 or -12-7 = -19

$\displaystyle \large{ m = 5, - 19}$

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,

$\displaystyle \large{ m > 5, m < - 19}$

2x+18-1=33 what is the awnser

Hitman42 [59]

<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>
