x - any unit in degrees
The ratio 7 : 8, therefeor the measures of the angles are 7x and 8x.
We know: the sum of those angles is 180°
Therefore we have the equation
7x + 8x = 180
15x = 180 |:15
x = 12
The smaller angle is 7x.
Your answer is 7 · 12° = 84°
Answer:
Daryl = 9, Malik = 3, Terrance = 14
Step-by-step explanation:
We can use letters to represent each brother's name, so
D + M + T = 26
3M = D
D + 5 = T
then we can plug in the 3M in the third problem for D
3M + 5 = T
Then we can go back to the first problem and plug in 3M and (3M + 5)
3M + M + (3M + 5) = 26
4M + (3M + 5) = 26
7M = 21
M = 3
plug 3 in for M in the second equation:
3 x 3 = D
D=9
Then go back to the first equation:
9 + 3 + T = 26
12 + T = 26
T = 14
So T = 14
D = 9
and M = 3
Answer:
<h2>x = 6, y = 42</h2>
Step-by-step explanation:
The diagonal divides both opposite angles into two angles. If ABCD is a parallelogram, then opposite sides are parallel, so we have alternate exterior angles.
Alternate exterior angles are congruent.
Therefore we have the equations:
4x = 24 and y - 10 = 32
4x = 24 <em>divide both sides by 4</em>
4x/4 = 24/4
x = 6
y - 10 = 32 <em>add 10 to both sides</em>
y - 10 + 10 = 32 + 10
y = 42

The position of A is located at : -3.75 explanation:
We know this because half of -3 and -4 it would be 50 but this is more than half way so if you count 25 cents more on a quarter it would be 75cents
