None of them really, but C is equivalent to the Triognometric Pythagorean Theorem:
That's the Trigonometric Pythagorean Theorem
Answer: C
Answer: by utilizing renewable resources.
Step-by-step explanation:
Example : using hydroelectricity and solar power as sources of energy may conserve mineral resources such as coal.
The slope is basically the coefficient of x and that is 1 since 1x=x. To find the y-intercept, you need to subtitute x=0 into y=x+5 because x is at 0 when you are looking at the y-intercept.
y=0+5=5
So the slope is 1 and the y-intercept is 5.
Diagonals of a rhombus
In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.
Answer:
x = 3
Step-by-step explanation:
There are two ways to do this. The simplest way is to realize that the exterior angle (45x) = the sum of the two remote interior angles.
25x and 57 + x
45x = 25x + 57 + x Subtract 26x from both sides.
45x - 26x = 25x - 25x + 57 Combine
19x = 57 Divide by 20
19x/19 = 57/19 Do the division
x = 3
===================================
Second method.
The supplement of the 45x angle is 180 - 45x
Now add the three angles together.
180 - 45x + x + 57 + 25x = 180 Combine like terms.
180 + 57 - 45x + x + 25x = 180
237 - 19x = 180 Subtract 237 from both sides.
- 19 x = 180 - 237 Combine the right side
- 19x = -57
x = 3
Good thing you made me redo it. Sorry!! I made an error. I lost 1 of the xs.
