Answer:
B. 38°
Step-by-step explanation:
The angles of a triangle add up to 180.
So, 62 + 80 + b will add up to 180.
First, we add 62 =80, which gives us 142.
The we subtract 142 from 180, which gives us 38.
Hi there!
When a segment is tangent to a circle, it is perpendicular to the radius. If you're given measurements, like the image below, you can use the pythagorean theorem to determine if the triangle is a right triangle. If the triangle is right, then the segment is tangent to the circle.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
LSA = 592cm^2.
Step-by-step explanation:
Well LSA is the SA but without the base so the blue square does not count.
So we have to find the area of the triangle which is b*h/2.
So 18.5*16 / 2 is 148.
And since there is 4 triangles with the same dimensions we do 148*4, 592cm^2.
What you want to do is simply identify the greatest common factor of 28 and 52
after factoring both all the way down, we see that this number is 4
so the maximum number of rows is 4
(there will be 7 amphibians and 13 snakes in each row)
