Answer:
a=30 b=30 c= 75
Step-by-step explanation:
By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.
Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.
So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180
Subtract 30 from both sides and you are left with:
2c = 150
Divide by 2 on each side:
c= 75
The answer is the second one
Answer:
a. base = 5 units; height = 4 units
b. base = 1 unit; height = 4 units
c. base = 1 unit; height = 4 units
Step-by-step explanation:
a. Count the bottom which is the base, which is 5, the height, or h would be the units or squares up which would be 4.
b. Count the only 1 on the bottom which then, base would be 1 because there is only one on the bottom, the rest is going diagonally so it doesn't count as the base. The height would be 4 because there are 4 units up.
c. Again, only 1 unit on the bottom so the base is one again, and 4 as the height again because of how much units high it is.
The only difference from b. to c. is that c. is having a different angle than b, but they are both the same!
I hope this helps!
