Use rectangle ABCD with diagonal DB. Find the measure of the angle marked x.

x = 41°

Step-by-step explanation:

A rectangle has 4 right angles, that is, each interior angle = 90°.

Therefore, the measure of the angle marked x is calculated as follows:

x + 49° + 90° = 180°

Solve for x

x + 139 = 180

Subtract 139 from each side

x + 139 - 139 = 180 - 139

x = 41°

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
