Its a 90 degree right angle because of how two of the segments in the triangle are shaped like a perfect letter L
A <span>45 45 90 triangle
so a = b
a^2 + b^2 = </span>c^2<span>
a^2 + a^2 </span>= c^2<span>
2a^2 </span>= c^2<span>
2a^2 </span>= 24^2
<span> 2a^2 = 576
a^2 = 288
a = 12</span>√2
b = a = 12√2
<span>
Area of triangle:
= 1/2 (</span>12√2)(12√2)
<span>= 1/2(288)
= 144
answer
Area = 144 ft^2
</span>
Answer:
no.
Step-by-step explanation:
a triangle can only have 180° in total but
60+60+63
=183°
Therefore a triangle can not have these three angles together.
Answer:11
Step-by-step explanation: Bases of trapezoid : 11 meters and 14 meters
height of trapezoid : 10 meters
Area of trapezoid = (sum of bases / 2) height
A = (11m + 14m)/2 * 10m
A = 25m / 2 * 10m
A = 12.5m * 10m
A = 125m²
