Answer:x-9
Step-by-step explanation:
Simplifying
Solving for variable
Move all terms containing x to the left all other terms to the right
Devide each side by 16
X=9
The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.
The sides of the triangle shown are AB and BC and the hypotenuse is AC,
so the correct answer would be:
(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169
Answer:
0.25.
Step-by-step explanation:
sin 30 = 0.5
So it is 2 * (0.5)^3
= 2 * 0.125
= 0.25.
Answer:
1/12
Step-by-step explanation:
The reason is, since drawing a red card and rolling a number cube don't affect the outcome of each other, you would multiply 1/2 by 1/6. 1x1=1 6x2=12 So the answer is 1/12
the sum of triangle is 180°
(2x-15)+(x-5)+42°=180°
2x+x-15°-5°+42°=180°
3x+22°=180°
3x=180°-22
3x=158°
x=52.67°
