Answer 1

Answer:

acute angle

Step-by-step explanation:

beacause one is 90 degree others are toral 90 degree

Answer 2

Answer:

∠A=90  

o

 

∠B=∠C (Give the triangle is isosceles)

In△ABC

∠A+∠B+∠C=180  

o

 

90+∠B+∠C=180  

o

 

∠B+∠C=90  

o

 

∠B+∠B=90  

o

 

2∠B=90  

Angle B=90/2=45

 

Hence, ∠B=45
