Question

Find the measures of the angles formed by two intersecting lines if the

Answer 1

Answer:

every single angle is 90°

Step-by-step explanation:

remember that,

4 angles will form if two lines intersect and the sum of those 4 angles is 360°

we are given the sum of 3 angles i.e 270

so one of the angles should be

$\displaystyle {360}^{\circ} - {270}^{\circ}$

simplify substraction:

$\displaystyle {90}^{\circ}$

therefore since one of the angles is 90° the intercepting lines are Perpendicular as a result every single angle formed by the two intercepting lines is 90°

Answer 2

Answer:

90°

Step-by-step explanation:

We know that sum of angle around a point is 360° . Here its already given that sum of three Angles out of 4 is 270°

Therefore :-

Measure of remaining one angle ,

• 360 - 270
• 90 °

Therefore the measure of the fourth angle is 90°
