Answer:
x=7
Step-by-step explanation:
This is a right triangle, we can use sin , cos, and tan
tan theta = opposite side/ adjacent
tan 45 = 7/x
Multiply each side by x
x tan 45 = 7/x *x
x tan 45 =7
Divide each side by 45
x tan 45 / tan 45 = 7/ tan 45
x = 7 / tan 45
x =7
Since line c and d are parallel, line a can act as a transversal. Thus, x=124 degrees because of the alternate exterior angle relationship that can be seen.
1.) false
2.) true
3.) false
Similar means equal angles and proportional sides
Triangles can be similar by SSS, AA or SAS
Answer:
x = 4
Step-by-step explanation:
Hello!
We can solve for x by expanding the parentheses and isolating x.
<h3>Solve for x</h3>
- 3x - 2(2x - 5) = 2(x + 3)-8
- 3x - 4x + 10 = 2x + 6 - 8
- -x + 10 = 2x - 2
- 10 = 3x - 2
- 12 = 3x
- x = 4
The value of x is 4.
