Since you’re already given one of the sides of the triangles as well as the triangle’s hypotenuse, you’ll want to find the third side to find the area.
To find the third side length, we’ll use the Pythagorean Theorem:
a^2 + b^2 = c^2
“a” and “b” can be used interchangeably, so we can substitute the known side length of 7 cm into “a”. 25 cm substitutes for “c” since it’s the hypotenuse.
(25)^2 - (7)^2 = c^2
c = 24
Area of triangle = (1/2)bh, where “b” and “h” are interchangeable.
Area of triangle = (1/2)(24)(7) = 84 cm^2

Answer:
x = 15°
Step-by-step explanation:
Due to Alternate Exterior Angles, we can tell that '5x = 75'. Now, let's simplify x.
=> 5x = 75
=> 5x/5 = 75/5
=> x = 15
Therefore, 'x = 15°'
Hoped this helped.
Answer:
- 1205 people per square miles
Step-by-step explanation:
- Population = 10 511 215
- Area = 8 723 square miles
<u>Population density is the number of people per unit of area:</u>
- 10511215 / 8 723 = 1205 people per square miles
Answer:
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
The radius is 1
Volume = 
or 4.19
Step-by-step explanation:
Given
Radius, r = 1
Required
Find the volume of sphere
Volume of a sphere is calculated using the following formula
Where V = Volume and r = radius
By Substitution,
Solving further to get the numerical value of volume;
We have to substitute 3.14 for π
V = 4.19 to the nearest hundredth
