Since this triangle is an isosceles triangle, two of its angles are going to be equal. We know that all the angles in a triangle are equal to 180o.
Step 1: 180 - 98 = 82
Step 2: divide the sum of the two angles (82) to give me the measurement of one of the angles
82/2 = 41
Answer:
228
Step-by-step explanation:
first we will find the area of the triangles on the sides of the prism.
(triangle area formula: (b*h)/2)
(6*5)/2 = 15
we multiply this by 2 since there are 2 sides that contain the same measures:
15*2 = 30
then we find the rectangles that are on the sides (not the base)
(rectangle formula: b*h)
11*6.5 = 71.5
multiply this by 2 since there are two sides:
71.5*2 = 143
finally we find the base using the same formula as we did to find the rectangles:
11*5 = 55
finally we add them all up:
30+143+55 = 228
hope this helps! :)
