Answer:
43°.
Step-by-step explanation:
To find the measures of the other two angles, we will need to use various angle properties.
We can use the Supplementary Angles formula to find the adjacent angle to the angle that measures 123°.
180 - 123 = 57°. This is the measure of the first angle.
Now, to find the measure of the second angle, we know that these are vertical angles meaning they are congruent. Therefore, the measure of the angle is 80°.
To find 'x', we will simply need to subtract from 180:
180 - 80 - 57 = 43°.
Let x be the unknown quantity. First, cross multiply to get 56x=392. Then divide both sides of the equation by 56 to get x=7.
Answer:
Step-by-step explanation:
As with any "solve for" problem, you undo what has been done to v, in reverse order. In this equation v has been ...
- multiplied by t
- had gt^2 subtracted from the product
So, the first step is to undo the subtraction by adding gt^2 to the equation:
h +gt^2 = vt
Now, we undo the multiplication by dividing by the coefficient of v.
(h +gt^2)/t = v
The answer for 1/2 divided by 9/4 is 2/9.
