Answer:

Step-by-step explanation:

J and K are equal

8x - 23 = 6x + 11 Add 23 to both sides

8x = 6x + 11 + 23 Combine the right

8x = 6x + 34 Subtract 6x from both sides

8x - 6x = 34 Combine the left

2x = 34 Divide by 2

x = 34/2

x = 17

=================================

M and L are both supplementary to J and K respectively.

J = 8x - 23

J = 8*17 - 23

J = 136-23

J = 113

K = 113

===================================

M + 113 = 180

M = 180 - 113

M = 67

L = 67

Two angles are supplementary. The measure of one angle is 4 more than 7 times the other angle. Find the measures of both angles.

mylen [45]

Answer:

The smaller angle measures 44° and the larger measures 136°

Step-by-step explanation:

Smaller angle = x

Larger angle = 3x + 4

Therefore, we have:

x + 3x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44 ⇒ 3x + 4 = 136

The smaller angle measures 44° and the larger measures 136°

kumpel [21]

Answer:

$\frac{11}{5}$

Step-by-step explanation:

Using the section formula

$y_{P}$ = $\frac{3(5)+7(1)}{3+7}$ = $\frac{15+7}{10}$ = $\frac{22}{10}$ = $\frac{11}{5}$
