Given m||n, find the value of x. (4x-7) degrees (3x+9) degrees It's transversal problems with equations Can anyone help please

Ratling [72]

Answer:

See explanation

Step-by-step explanation:

Given

$\angle 1 = 4x - 7$

$\angle 2 = 3x + 9$

Required

Find x

The question is incomplete, as the relationship between both angles is not given

(1) If they are supplementary, then

$\angle 1 + \angle 2 = 180$

$3x + 9 + 4x - 7 = 180$

Collect like terms

$3x + 4x = 180+7-9$

$7x = 178$

Divide both sides by 7

$x = 25.43$

(2) If they are complementary, then

$\angle 1 + \angle 2 = 90$

$3x + 9 + 4x - 7 = 90$

Collect like terms

$3x + 4x = 90+7-9$

$7x =88$

Divide both sides by 7

$x = 12.57$

(3) If they are vertically opposite angles, then

$\angle 1 = \angle 2$

So, we have:

$4x - 7 = 3x + 9$

Collect like terms

$4x - 3x = 9 +7$

$x = 16$

John is trying to estimate how tall a tree is. the shadow created by the tree is 18 feet long. john is 6 feet tall, and his shad

Alecsey [184]

Make a comparison
$\frac{height}{shadow}= \frac{height}{shadow}$
$\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}$

Plug the numbers into the equation above
h stands for the height of tree
$\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}$
$\frac{h}{18}= \frac{6}{3.5}$

Do cross multiplication
3.5h = 6 × 18
3.5h = 108
h = 108/3.5
h = 30.8571..

to the nearest hundredth
h = 30.86 feet
to the nearest tenth
h = 30.9 feet

Lev has 9 tens . Jim has 1 ten. They put all their tens together. Dawn puts 9 ones with the tens. What number did they make?

Olegator [25]

The answer would be 109. 9 tens is 90, and 1 ten is 10, 90+10=100 plus the 9 ones that Dawn put, 109
