D is the only one not true
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: b=4(10)^1/2
Step-by-step explanation:
Distance Formula: a^2+b^2=c^2
6^2+b^2=14^2
36+b^2=196
b^2=160
b^2=10*16
b=(10*16)^1/2
b=4(10)^1/2
Answer:
Step-by-step explanation:
example :
2 1/4 + 3 1/2
you can either turn them to improper fractions, find the common denominator, and then add them and then convert that answer to a mixed number
2 1/4 + 3 1/2 = 9/4 + 7/2 = 9/4 + 14/4 = 23/4 = 5 3/4
OR
separate them....add the whole numbers, then the fractions
2 1/4 + 3 1/2 .......2 + 3 = 5.....1/4 + 1/2 = 1/4 + 2/4 = 3/4.....now put them back together and u get : 5 3/4
