Pachacha [2.7K]

Answer:

The Pythagorean Theorem leads to a simple proof of the Pythagorean Identity using only the basic definitions of trig functions. The Pythagorean Theorem on a right triangle with legs a,b and hypotenuse c gives us: a2+b2=c2. Dividing through by c2 gives: (ac)2+(bc)2=1.

Somebody help me with this

Alchen [17]

<u>Given</u>:

Given that the quadrilateral ABCD is inscribed in the circle.

The measure of ∠A is (14z - 7)°

The measure of ∠C is (8z)°

The measure of ∠D is (10z)°

We need to determine the measures of ∠A, ∠B, ∠C and ∠D

<u>Value of z:</u>

We know the property that the opposite angles of a quadrilateral inscribed in a circle are supplementary.

Thus, we have;

$\angle A+ \angle C=180^{\circ}$

Substituting the values, we have;

$14z-7+8z=180$

$22z-7=180$

$22z=187$

$z=8.5$

Thus, the value of z is 8.5

<u>Measure of ∠A:</u>

The measure of ∠A can be determined by substituting the value of z.

Thus, we have;

$\angle A=14(8.5)-7$

$\angle A=119-7$

$\angle A=112^{\circ}$

Thus, the measure of ∠A is 112°

<u>Measure of ∠C:</u>

The measure of ∠C can be determined by substituting the value of z.

Thus, we have;

$\angle C=8(8.5)$

$\angle C =68^{\circ}$

Thus, the measure of ∠C is 68°

<u>Measure of ∠D:</u>

The measure of ∠D can be determined by substituting the value of z.

Thus, we have;

$\angle D=10(8.5)$

$\angle D=85^{\circ}$

Thus, the measure of ∠D is 85°

<u>Measure of ∠B:</u>

The angles B and D are supplementary.

Thus, we have;

$\angle B+ \angle D=180^{\circ}$

Substituting the values, we get;

$\angle B+ 85^{\circ}=180^{\circ}$

$\angle B=95^{\circ}$

Thus, the measure of ∠B is 95°

A rectangular red sticker has a perimeter of 12 millimeters and an area of 8 square millimeters. What are the dimensions of the

bekas [8.4K]

Answer: 9" by 7"

Step-by-step explanation:

let the dimensions of the rectangle be x and y

equation 1: xy=63

equation 2: 2(x+y)=32

first, rearrange the terms

(1′): y=63/x

(2′): y=16−x

(1′)-(2′): 0=63/x−16+x

multiply the equation by x

0=x2−16x+63

0=(x−9)(x−7)

so x = 7 or x = 9

from this, y = 9 when x = 7 and y = 7 when x = 9

so, the dimension of the rectangle is 9″ by 7″
