Answer:
23.0 =x
Step-by-step explanation:
Assuming this is a right triangle
cos theta = adj/ hypotenuse
cos 23 = x/25
Multiply each side by 25
25 cos 23 = x
23.01262134 =x
To the nearest tenth
23.0 =x
Answer:#1 C.30 #2 40
Step-by-step explanation:
3x+15=7x-5
3x+15+5=7x-5+5
3x+20=7x
3x-3x+20=7x-3x
20=4x
20/4=4/4x
5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30
So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180
4x-48+3x+4=180
7x-44=180
7x=224
x=32
2(32)-24
64-24=40

Answer: 21
1) simplify 6+4 to 10
10+6+5
2) simplify 10+6 to 16
16+5
3) simplify

Answer: Yes it is a solution
Work Shown:
Replace x with -2, replace y with 2. Simplify.
y > (1/2)x - 2
2 > (1/2)*(-2) - 2
2 > -1 - 2
2 > -3
The last inequality is true, so the original inequality is true when (x,y) = (-2,2)
This makes (-2,2) a solution to the inequality.
