Answer:
part 7 = 15cm
Step-by-step explanation:
So firstly you are given the external angles, to find the internal angles, you do 180-133=47
180-142=38
the internal angles in a triangle add up to 180, therefore it is
47+38=85
180-85=95
because you have to find the external angle=n you then need to take 95 away from 180
180-95=85
so the answer is A
The answer is nine because eighteen subtract nine is nine
Answer:
40
Step-by-step explanation:
s = 2;
h = 4
Surface area = 2s² + 4sh
= 2*2² + 4 * 2 * 4
= 2 *4 + 32
= 8 + 32
= 40 sq. units
