The measure of angle 1 is 30°, and the measure of angle 2 is 110°. what is the measure of angle 4? a. 40° b. 80° c. 140° d. 220°

the correct option is A)

Step-by-step explanation:

Given : - Measure of angle 1 is 30°, and the measure of angle 2 is 110° .

We need to find the the angle 4

Since, The sum of interior angles of triangle is

Subtract both the sides by

Hence, the correct option is A)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
