Answer:
The answer is B.
Step-by-step explanation:
Recall SohCahToa, where 
.
The opposite side (to angle A) here is 8, while the hypotenuse is 10.
Thus, we have:
The correct answer is B.
Hi,
Let's start with the equation:
(7)(11)+(3)(3)−16/2
Next multiply:
=77+(3)(3)−16/2
=77+9-16/2
Add:
=86−16/2
=86−8
=78
Have a great day!
Answer:
For any circle of radius r
The diameter of the circle = two times of the radius = 2r
And The Circumference= C = 2πr
14. If r = 8
So, d = 2r = 2 * 8 = 16 cm
C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)
15. If d = 9 m
So, d = 2r
∴ r = d/2 = 9/2 = 4.5 m
And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)
Short answer = false
Remark
If it is a right triangle, it will obey the Pythagorean Equation. a^2 + b^2 = c^2. Let's see if it does.
Equation
a^2 + b^2= c^2
c must be the longest line. (Hypotenuse)
Givens
a = 24
b = 17
c = 40
Sub and Solve
a^2 + b^2 = c^2
17^2 + 24^2 = c^2 [We'll see if this comes out to 40]
289 + 576 = c^2
865 = c^2 which is no where near what 40^2 equals. 40^2 = 1600
Short answer False
Square root of 865 = (865)^1/2 = 29.4
Answer:
10
Step-by-step explanation:
Area of traingle:1/2
50=1/2.10.x
50=5x
50/5=5x/5
50/5=5x/5
x=50/5
x=10
