PLEASE HELP ME!!!!!!!

Mathematics
1 answer:
Viefleur [7K]3 years ago
5 0

Answer:

Step-by-step explanation:

x^2 + 2x = 6x+45

x^2 -4x -45 =0

x^2 - 5x +9x -45 =0

x(x-5) +9 (x-5)=0

(x-5)(x+9)=0

x = 5, -9

x = 5; measure of exterior angle = 5^2+2(5) = 35

x=-9; measure of exterior angle  = (-9)^2 + 2(-9) = 63

In the following figure find the area of shaded portion​
Anon25 [30]

Answer:

90 cm²

Step-by-step explanation:

The area of the shaded portion is the area of parallelogram ABCD minus the area of triangle EBC.

ABCD is a parallelogram with base 18 cm and height 10 cm.

A(parallelogram) = bh = (18 cm)(10 cm) = 180 cm²

EBC is a triangle with base 18 cm and height 10 cm.

A(triangle) = bh/2 = (18 cm)(10 cm)/2 = 180 cm²/2 = 90 cm²

shaded area = 180 cm² - 90 cm² = 90 cm²

Need help with this please
Katarina [22]

Answer:

The third side is sqrt(77)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

2^2 + b^2 = 9^2

4+ b^2 = 81

Subtract 4 from each side

b^2 = 81-4

b^2=77

Take the square root of each side

sqrt(b^2) = sqrt(77)

b = sqrt(77)

The third side is sqrt(77)

Find the area of the smallest side of the right<br> triangle.<br> A = 169 ft²<br> A = 144 ft²
Ghella [55]

The area of the smallest side of the right triangle is 25 ft².

<h3>What is a right-angle triangle?</h3>

A triangle having two sides at an angle of 90 degrees is called the right-angle triangle.

Note:- The figure is missing in the question I am attaching the complete figure with the answer below for calculation.

Given that:-

The hypotenuse = 169 ft ²  = 13 ft

The side with area 144 ft²   = 12 ft

Using Pythagoras' identity to find the third side x ( smallest )

x² + 12² = 13²

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = 5

Thus the area of the smallest side will be calculated as:-

A =  5²

A =  25 ft²

Therefore the area of the smallest side of the right triangle is 25 ft².
