Answer:

x=12

Triangle abc and Def are congruent but different sizes. The original triangle has side values of 2, 6 and 5. Then the shape is dilated by an unknown factor, giving it the side lengths of 4, x, and 10. Looking at the increase in side lengths we see that theres an increase of 2 to 4, or multiplying by 2 and an increase from 5 to 10, or multiplying by to. So now that we know there was a dilation of 2, we multiply 6 by 2 to find 12

Answer:

First box = 22.5, 45/2, or 22 and 1/2

Second box = square inches (because area is always ^2, or squared)

Step-by-step explanation:

A = B * H

B = base

H = height

Base = 5 inches

Height = 4.5 inches

5 inches * 4.5 inches = 22.5 inches^2

This can also be written as 45/2 or 22 and 1/2

Which equation has NO solution? A) 15x + 12 3 = 5x + 4 B) 8 − 4x 10 = 4 + 2x C) 4x − 20 2 = 2x − 10 D) 15x + 5 3 = 5x + 6

Assumption:

Something is missing in question. If we see deeply it is apparent that there is some issue with option b i.e. B) 8 − 4x 10 = 4 + 2x we assume that the questioner want to type B) 8-4x^10 = 4 + 2x.

Answer:

The correct answer is B) 8-4x^10 = 4 + 2x.

Step-by-step explanation:

All equations given is the question can be solve easily to determine the value of x. However if we solve equation mentioned in option b we cannot get single answer easily.

For example value of x in eq given in option A

15x + 123 = 5x+4

1oX = -119

X = -119/10

1-cos^2 A / sec^2 A - tan^2 A

tiny-mole [99]

I hope this helps you

✔cos^2A+sin^2A=1

✔1-cos^2A=sin^2A

✔cos2A=cos^2A-sin^2A

✔sin2A=2.sinA.cosA

secA=1/cosA

tgA=sinA/cosA

sin^2A/1/cos^2A-sin^2A/cos^2A

sin^2A.cos^2A/cos2A

2.sin^2A.cos^2A/cos2A

sin2A.2.sin2A/cos2A
