what is the value of the missing angle? (I don't know what you call this shape but its like drawing a house on paper but its upside down ex: the triangle is on the bottom and the square is on top. where the triangle is theres a number 140 on each side and the point part has a x where you have to find the value.
A. 80
b. 90
c 170
d. 260
how do I do this?
Made a mistake its 80
the answer is 80 degrees.
what is the answer?
‘~.~ I’m so confused
these are the answers i got witch one is it
A 50
B 60
C 100
D 240
It’s c.
What is the value of the missing measure?
To find the value of the missing angle in the shape you described, we need to use the fact that the sum of the angles in a triangle is 180 degrees.
Given that each side of the triangle has an angle measure of 140 degrees, we can determine the missing angle as follows:
1. Subtract the known angle measures from 180 degrees to find the sum of the other two angles in the triangle:
180 - 140 - 140 = 180 - 280 = -100 degrees
2. Since an angle cannot have a negative measure, we need to adjust the calculation to account for that. By adding 360 degrees to the negative sum, we obtain the positive version of the same angle:
-100 + 360 = 260 degrees
Therefore, the value of the missing angle is 260 degrees. Thus, the correct option is (d) 260.
90
the triangle has three equal sides, then it is equilateral, so each of its angles is 60°
The square's angles are all 90°.
So, starting at the bottom of the triangle, and moving around, the angles are
60, 60+90=150, 90, 90, 150
Note that as with any pentagon, the sum of the angles if 540°.
If the x is not a corner of the square, I don't see how any of the other values can be chosen. From the description given, I can't come up with any of the other values than 90°.
