Question

∆ABC is a right angle trianle. If angle b is 90°. Find angle A and angle C ?

plz give me the ans with full solution ​

Answer 1

in ∆abc

∆ ABC is a right angle

therefore

angle a 60°,angle b 90°,angle c30°

because 30° 60° 90° therom

Answer 2

Answer:

The measure of ∠A and ∠C is $45^{0}$.

Step-by-step explanation:

Given : ∆ABC is a right angle triangle.

           m∠B = $90^{0}$

To find : m∠A and m∠C.

Solution :

• It is given that ∆ABC is a right angle triangle.

           m∠B = $90^{0}$

• We have to find m∠A and m∠C.
• Let, $x$ be the measure of ∠A and ∠C.
• We know that in a right angled triangle, the sum of all the three angles is $180^{0}$.
• The required equation becomes,

            ∠A + ∠B + ∠C = $180^{0}$

                 ∴ $x+90+x=180$

                     ∴  $2x+90=180$

                            ∴  $2x=180-90$

                            ∴  $2x=90$

                             ∴  $x=\frac{90}{2}$

                              ∴ $x=45^{0}$

• ∴  The measure of ∠A and ∠C is $45^{0}$.
