2 triangles measure 55 and 20 what is the measure of the third angle

x = 105

Step-by-step explanation:

The angles of a triangle add to 180 degrees

Let x be the third angle

55+20 +x =180

75 +x = 180

x = 180-75

x = 105

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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,
