Answer:
x = 24
obtuse isosceles triangle
Step-by-step explanation:
x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.
180-132 = 2x
48 = 2x
x = 24
It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.

You measure two quantities as A=1.0m±0.2m, B=2.0m±0.2m. We should report correct value for
AB
as
Medium

Correct option is
D
1.4m±0.2m
Here, A=1.0m±0.2m, B=2.0m±0.2m
AB=(1.0m)(2.0m)=2.0m

=1.414m
Rounding off to two significant figures, we get

Answer:
73.74°
Step-by-step explanation:
sin Ф = opposite/hypotenuse
sin Ф = 24/25
(24/25) = 73.74

9 times 16 = 144
2(9+16)= 50
smallest possible perimeter is 50(whatever unit you're doing)
