Answer:
B—283 cm^2
Step-by-step explanation:
SA=πr^2 + πrl
r=5
l=13
SA=π5^2 + π5*13
SA=π25 + π65
SA=78.5398 + 204.2035
SA=282.7433
SA=283=B
Answer:
.
Explaining:
The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle.
In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.
There are 180 degrees in a triangle, so what you want to do from there is make an equation 35 + 65 + 2x = 180 from there add like terms 100 + 2x = 180 then subtract 100 from 180 to get 2x alone 100 - 100 + 2x = 180 - 100
2x = 180 from there divide 2 from 180 and get the answer x = 78 degrees
Answer:
=5.2/1.3
=4
16/4
=4
Step-by-step explanation:
first find the ratio of 5.2 to 1.3 by dividing the 2 numbers. That gave me 4 since you want EF I just did 16 divided by 4 which gave me 4.
EF=4
Answer:
Yes, they are parallel
Step-by-step explanation:
You can rewrite the second equation in slope intercept form to get your answer.
x-2y-8=0
-2y=-x+8
y=1/2x-4
Since the slope of this line is the same as that of the first, they are parallel. Hope this helps!
