Answer:
It would be 29.
Step-by-step explanation:
Angle B = 60°
The complement of angle B is 90 - x.
60° + (90 - x)° = 180°
Can you take it from here?
Answer:
40 degrees
Step-by-step explanation:
The sum of the angles is 180.
A 100 degree angle cannot be a base angle because then
the sum of the base angles would be 200 degrees.
The 100 must be the vertex angle.
Equation:
x + x + 100 = 180
2x = 80
x = 40 degrees.
Each of the base angles is 40 degrees.
Answer:
There are 60 lemon cookies.
Step-by-step explanation:
1/2/240=120
3/20/240=36
1/10/240=24
120+36+24=180
240-180=60
