Answer:
The first angle is 90 degrees. The second angle is 80.
Step-by-step explanation:
To find the first angle, we know that the missing angle is a right angle. Right angles are 90 degrees. For the second angle, the triangle is a scalene triangle which contains a total of 180 degrees. 180-100=80.
Here
Length = x+3
Breadth = x
We know
Perimeter of reatangle = 2(l+b)
Or 34 = 2( x+3+x)
Or 17 = 2x+3
Or 14 =2x
Or x= 7
Therefore
Length = 10 and breadth = 7 cm
