-Todo ❤️

Step-by-step explanation:

90+32+4+6x=180

-126. -126

6x=54

X=9

9=x
Minutes 32 from 90
You get 54 so set your equation to 58
6x+4=58
Minus four from both sides
6x=54
Divide by 6 to get the variable by itself
x=9

The area of the triangle below is 5/12 square feet. What is the length of the base? Express your answer as a fraction in simplest form.

Answers

Answer:

5/3 ft

Step-by-step explanation:

a = (1/2)bh

5/12 = (1/2)(1/2)h

5/12 = 1/4h

Multiply bith sides by 4

20/12 = h

h = 20/12

Reduce

h = 5/3 ft

Answer:

base = 5/3

Step-by-step explanation:

length= x

area triangle =

(bxh)/2

5/12 = x (1/2) divide by 2

Multiply both sides by 1/2 to isolate x

10/12 = 1/2 x

Multiply by 2

20/12 = x

5/3 = x

A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.

Answers

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The ladder is making a right-angle triangle with a wall as shown below.

By Pythagoras's theorem,

x² = 30² - 24²

x = 18

By Pythagoras's theorem,

y² = 30² - (18 + 10)²

y = 10.77 feet

Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".
