lines ab and cd are perpendicular to each other. if 1 measures (3x + 3)°, and 2 measures 30°, what is the value of x?
a.
x = 120
b.
x = 11
c.
x = 19
d.
x = 60

C

Step-by-step explanation:

Since AB and CD are perpendicular to each other, then

∠ 1 + ∠ 2 = 90°, that is

3x + 3 + 30 = 90

3x + 33 = 90 ( subtract 33 from both sides )

3x = 57 ( divide both sides by 3 )

x = 19 → C

C

Step-by-step explanation:

Lines AB and CD are perpendicular to each other.So,

∠1 + ∠2 = 90

3x + 3 + 30 = 90

3x +33 = 90

3x = 90 -33

3x =57

x = 57/3

x= 19

55

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
