9/12 is number 1. and Number 2 is 1/2 =4/8 and that is 1/2
Hey there! :)
The total measure for triangles is 180°
You already know 2 angles. Add both angles and subtract from 180 to find x
37 + 82 = 119
180 - 119 = 61
m∠x = 61°
Hope this helps :)
Which one is question 20??
Answer:

Step-by-step explanation:
Given that,
Radius of a cone, r = 13 cm
Slant height of the cone, l = 20 cm
We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

Put all the values,

So, the surface area of the cone is
.
Answer:
x = 14.25
Step-by-step explanation:
Start with a^2 + b^2 = c^2
a = 11
b = x
c = 18
plug in and solve
11^2 + x^2 = 18^2
121 + x^2 = 324 - Simplify
x^2 = 203 - subtract 121 from both sides
x = 14.247 rounds to 14.25 - square root on both sides
