Answer: 16 m
Step-by-step explanation:
Using the Pythagorean theorem you can find the height of the mast.
The formula is;
a² + b² = c²
a is one side of the triangle such as the width
b is another side such as the height
c is the hypotenuse which is the longest side.
c will therefore be 20m.
a will be 12m
12² + b² = 20²
b² = 400 - 144
b² = 256
b = √256
b = 16m
Answer:
8
Step-by-step explanation:
we conformed the 8s by 4 and 3
Answer:
its d, because there is no hypotenus in equiateral but there hypotenues in right triangle
Step-by-step explanation:
Answer
5
Step-by-step explanation:
8n+10=50
-10 -10
8n=40
8n/8 = 40/8
n= 5
She will be able to buy 5.
DOUBLE CHECK:
8(5)+10=50
40+10=50
50=50
