Find the value of x plsss the people that answerd this got it wrong.

155°

Step-by-step explanation:

The total of the angles in a triangle is 180° and also any pair or trio of angles that maje a straight angle also add up to 180°. So look for those set ups.

The left most triangle has an angle marked 35° and also a right angle is labelled. The right angle is 90° So the third angle must be 180° - (35°+90°)

180° - 125°

55°

The 55° angle(we just found) and the 60° angle (labelled) and a third unmarked angle all together maje a straight angle, 180°.

So we can calculate the third angle, which is an angle in the other shown triangle.

180° - (55° + 60°)

180° - 115°

65°

This triangle also has a right angle in it. And the third angle can be calculated in the same way.

180° - (65° + 90°)

180° - 155°

25°

Last time, the 25° angle and the angle marked x make a straight angle.

180° - 25°

155°

it would open into a square depending on the type of envelope i’m not sure about the second part

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
