Question

in ∆ PQR <P = 37° , <Q = 56° then < R = ?
please give me answer ​

Answer 1

Answer:

37°+56°+X=180(triangle)

=X=180-37°-56°

=x°=87°

Step-by-step explanation:

checking

37°+56°+87=180°

if the answer is correct then please mark me as brainlist...

Answer 2

Given:-

• In ∆PQR ∠P is 37°.
• And ∠Q is 56°.

To find:-

• Measure of ∠R

Solution:-

We know that,

Sum of all interior angles of triangle is equal to 180°. This property is also known as 'Angle sum property of triangle'.

So,

➔ ∠P + ∠Q + ∠R = 180°

➔ 37° + 56° + ∠R = 180°

➔ 93° + ∠R = 180°

➔ ∠R = 180° - 93°

➔ ∠R = 87°

Verification:-

➔ ∠P + ∠Q + ∠R = 180°

➔ 37° + 56° + ∠R = 180°

• Put ∠R = 87°

➔ 37° + 56° + 87° = 180°

➔ 180° = 180°

Hence, Verified.

Therefore,

∠R is of 87°.

More information:-

• Above triangle is an Scalar triangle beacuse it's all angles are unequal.

• If it's all angles will equal then It will be equalitral triangle.

• If it's two angles will equal then it will be Isosceles triangle.
