Answer:

1/cos^2(180-theta) - 1

Step-by-step explanation:

According to trigonometry identity

tan^2 theta + 1 = sec^2 theta

tan^2 theta = sec^2 theta - 1

hence tan^2(180-tetha) = sec^2 (180 -theta) - 1

tan^2(180-tetha) = 1/cos^2(180-theta) - 1

Hence the value of tan^2(180-tetha) is 1/cos^2(180-theta) - 1

Answer:

Step-by-step explanation:

x^2 + 2 = 6x - 6

x^2 - 6x + 2 + 6 = 0

x^2 - 6x + 8 =0

(x - 4)(x - 2)

alex41 [277]

Answer:

$0.8\ m$

Step-by-step explanation:

In this problem we know that

The scale is equal to

$\frac{1}{250}\frac{m}{m}$

by proportion

Find what will be the height of the scale model

$\frac{1}{250}\frac{m}{m}=\frac{x}{212}\frac{m}{m}\\ \\x=212/250\\ \\x= 0.848\ m$

Round to the nearest tenth of a meter

$0.848\ m=0.8\ m$
