Answer:
9/4
Step-by-step explanation:
1 2/7=9/7
2 1/3=7/3
--------------
9/7+7/3x+3/14+x=9
18/14+3/14+7/3x+3/3x=9
21/14+10/3x=9
10/3x=9-21/14
10/3x=9-3/2
10/3x=18/2-3/2
10/3x=15/2
x=(15/2)/(10/3)
x=(15/2)(3/10)
x=45/20
simplify
x=9/4
Answer:
c) Right
Step-by-step explanation:
An Right triangle is a triangle with an angles being 90 degrees and we know that 2 of the angles are 59 and 31 and we know that the sum of all the angles in a triangle will equal 180 so 180-59-31 = 90 so this triangle has a 90 degree angle making it a right triangle
The answer is the first one
1. x = 25 inches
2. Triangle c
