Answer:

C) 5

Step-by-step explanation:

As the horizontal lines are parallel, the ratio of the segments will be constant.

3/(3 + 4) = (x - 1)/14

3(14) = 7(x - 1)

42 = 7x - 7

7x = 35

x = 5

Answer:

$x = 51^o$

Step-by-step explanation:

Given

Intersecting lines

Required

Find x

To do this, we make use of:

$x + 23^o + 2x + 4^o = 180^o$ --- angle on a straight line

Collect like terms

$x + 2x = 180^o - 4^o - 23^o$

$3x = 153^o$

Divide both sides by 3

$x = 51^o$

Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The student is 6 feet tall. What is the height of the tree? Show all work

Answer:

Option D

The height of tree is 20 feet tall

Solution:

From given question,

Shadow of tree = 30 feet

Height of tree = ?

Height of student = 6 feet

Shadow of student = 9 feet

We have to find the height of tree

We can solve the sum by proportion

$\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}$

This forms a proportion and we can solve the sum by cross multiplying

$\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20$

Thus height of tree is 20 feet tall
