0Given That The Triangles Are Similar, Find The Value Of X. Find The Length Of NR.ST4060R2x-28NMX=NR

Answers

Answer 1

Answer:

NR = 12

Step-by-step explanation:

Given that both trjangles are similar, therefore, it follows that their corresponding side lengths would be proportional to each other. Thus:

[tex] \frac{40}{8} = \frac{60}{2x - 2} [/tex]

[tex] 5 = \frac{60}{2x - 2} [/tex]

Cross multiply

[tex] 5(2x - 2) = 60 [/tex]

[tex] 10x - 10 = 60 [/tex]

[tex] 10x = 60 + 10 [/tex] (addition property of equality)

[tex] 10x = 70 [/tex]

Divide both sides by 10

x = 7

✔️NR = 2x - 2

Plug in the value of x

NR = 2(7) - 2 = 14 - 2

NR = 12

Explain why 3 x 4 and 3+3+3+3 equal the same answer.

Answers

Step-by-step explanation:

Because

3×4=12

and

3+3+3+3=12

are same. For easy calculations we use 3×4

Multiplication is repeated addition.3 x 4 is the same as four 3s being added together.4 x 3 is the same as three 4s being added together.3 + 3 + 3 + 3 = 123 x 4 = 124 + 4 + 4 = 124 x 3 = 12

HELP ME PLZZ MARKING BRAINLIEST:) 7TH GRADE MATH

Answers

Correct answer:

8cm

Explanation:

Because the two trapezoids are similar, the ratio of their bases must be the same. Therefore, we must set up a cross-multiplication to solve for the missing base:

6x=912, using x as the variable for the missing base.

72=9x

x= 8

Therefore, the length of the longer base of Trapezoid B is 8cm.

If sec x = -3, and x lies in quadrant II, find tan
x/2

Answers

Answer:

√2.

Step-by-step explanation:

sec ^2x = 1 + tan^2 x

(-3)^2 = 1 + tan^2x

tan^2 x = 8

tan x = +/- 2√2

tan x/2 =  tanx / sec x + 1

= -2√2 /  -3 + 1

= -2√2 / -2

= √2

We take the negative tan  because tan is negative in the second quadrant.
