Answer:
x=45
Step-by-step explanation:
Each triangle had 180 degrees in all and the picture shows it has a right angle. 180-90=90
90/2=45
Because there are two angles left without measurement.
Answer: I think the answer is D
Step-by-step explanation:
9514 1404 393
Answer:
52°, 40°, 88°
Step-by-step explanation:
Let x represent "one angle". This is 30% larger than "the other", so we have ...
x = "the other" × (1 +30%)
x/1.30 = "the other"
If x is 36° smaller than the third, then the third is x+36.
__
The sum of the angles is 180°.
x + x/1.3 + (x +36) = 180
x(2 +1/1.3) = 144
x = 144/(2 +1/1.3) = 52
x/1.3 = 52/1.3 = 40
x +36 = 88
The angles of the triangle are 52°, 40°, and 88°.
I don’t know I really don’t know, I am very confused ahhhhhhh!
Answer:
x = 25.5 degrees
Step-by-step explanation:
x is part of an isosceles triangle.
Since a is 51, the supplement (& biggest angle in the x isosceles) is going to be 180 - 51 = 129.
That leaves 51 for the rest of the angles, which we have to divide by 2.
51 / 2 = 25.5 degrees
