Answer» ong>Answer: Step-by-step explanation:GIVEN:l∥m
sum of the interior angles on the same SIDE of transversal is 180 ∘
b+52 ∘ =180 ∘
⇒b=180 ∘ −52 ∘ =128 ∘
And a=52 ∘
∴a=52 ∘ ,b=128 ∘

In a right angled triangle ABC, angle B = 90°. If AB= 8, BC = 15,find the perimeter of ∆ ABC. |
|
Answer» ong>Step-by-step explanation: AB = 8 units BC = 15 Units As angle B is 90° so , CB is hypotenuse so ACCORDING to Pythagoras theorem, H^2 = P^2 + B^2 CB^2 = AB^2 + BC^2 CB^2 = 8^2 + 15^2 = 64+225 = 289 CB = √289 CB = 17 Now, Perimeter of triangle = SUM of all sides so Perimeter of triangle ABC = AB+ BC+CB = 8+15+17 = 40 units |

In a right angled triangle where angle A= 90° and AB=AC. What are the values of angle B. |
|
Answer» ong>Step-by-step explanation: Given ∆BAC is a triangle right angled at A. AB = AC This means it is a isosceles triangle with BASE and height of same length. In this case the opposite angles must be equal and adds up to 90°. why? Because one 90° is already FIXED at Angle A. The remaining Angle B and C must be equal and adds up to 90° to fulfill the angle SUM property of a triangle. We KNOW 90° = 45° + 45° So, angle B = 45° |
