Answer:
x = 14
Step-by-step explanation:
I don't know which one you are supposed to solve it by so I will do both.
Solution by Cross Multiplication
For the equation
7x=24
The cross product is
7×4=x×2
Solving for x
x=7×42
and reducing
x=14
Solution by Proportion
Since the equation is an equality
If
7 ÷ 2 = 3.5
Then it is true that
x ÷ 4 = 3.5
Solving for x
x = 4 × 3.5
x = 14

Answer:
Step-by-step explanation:
Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.
