Answer:

13 degrees.

Step-by-step explanation:

First we calculate the other 2 angles of the triangle of which < x is a part.

The bottom angle = 85 (vertical angles are equal).

The top one = 180 - 98 = 82. ( corresponding and adjacent angles).

So angle x = 180 - (85 + 82).

= 180 - 167

= 13 degrees.

Find the measure of the side of the right triangle whose length is designated by a lowercase letter. (see attachment)

PilotLPTM [1.2K]

Answer:

a≈18 cm

Step-by-step explanation:

we have given:

an angle,

the adjacent side and

we need to find:

the opposite side

we know that the definition of

tan of an angle = opp. side/ adj. side

tan 61° = a/ 10

multiply both sides by 10

10 * tan61° = a

18.04047755 = a

18 ≈ a
