Question

This question from maths

Answer the following.

(1.) What is the measure of the complementary angle of 51 degree?

(2.) If two lines intersect each other at a point then how many corresponding angles will be formed?

(3.) If two lines intersect each other and one angle of vertically opposite angles pair is 125 degree then what will be measurement of another angle?

Answer 1

Answer:

(1) 39  (2) 0  (3) 125

Step-by-step explanation:

for 1

comlementry angle = 90

let the other angle to be x

so 90 = x +51

90 - 51 = x

39 =x

for 2

they did not cut by any transversal

so corresponding anglrs are 0

for 3

voa are equal in measure

so if one angle is 125 than other will also be 125

hope it helps....

Answer 2

Answer:

1. We know, Two angles are complementary if their sum is = 90 degrees

Here, one angle = 51 degree { given}

Let the other angle be x.

Then, 51 + x = 90 degree

or, x = (90 - 51 )

= 39 degrees.

2. The eight angles will together form four pairs of corresponding angles. Like : Angles F and B in the figure above constitutes one of the pairs.

As in this case where the adjacent angles are formed by two lines intersecting we will get two pairs of adjacent angles (G + F and H + E) that are both supplementary.

3.  The other angle will also be 125 degree.

( Reason : Since Vertically Opposite angles are equal.)
