Consider a ABC right angled at C and
Then,
‣ Base [B] = BC
‣ Perpendicular [P] = AC
‣ Hypotenuse [H] = AB
Let,
Base = 7k and Perpendicular = 8k, where k is any positive integer
In ABC, H² = B² + P² by Pythagoras theorem

we know that the shaded side is 90 degrees and we are given 28 degrees
So we add 90+28 and we get 118
Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure
180-118=62
x=62
Your equation is 180=90+28+x
The answer would be x= 68 degrees
Answer:
91 Adults
Step-by-step explanation:
Because there are 26 children, you divide it by 2 to get 13. Multiply 13 by 7 for your answer, 91
The surface area<span> of a right </span>prism<span> can be calculated using the following formula: SA 5 2B 1 hP, where B is the </span>area<span> of the base, h is the height of the </span>prism<span>, and P is the perimeter of the base. The </span>lateral area<span> of a figure is the </span>area<span> of the non-base faces only.</span>
