Can somebody me with these two questions? and show your work ?

solve for x.

(1)   x = 12,   (2)  

Solution:

(1)     If the two triangles are similar and the angles of two triangles are congruent then the corresponding sides are in proportion.

⇒

Do cross multiply.

⇒

Divide both sides of the equation by 25 to equal the expression.

⇒

⇒ x = 12

(2)   Side of triangle =

If the two triangles are similar and the angles of two triangles are congruent then the corresponding sides are in proportion.

⇒

Do cross multiply.

⇒

⇒

Divide both sides of the equation by 26 to equal the expression.

⇒

⇒

⇒

96 39 cause 135 -96=39 im smart (i used a calculater)

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )
