Answer:
35 cm^2
Step-by-step explanation:
Area of roof=(5*4)/2=20/2=10 cm^2
Area of square=(5*5)=25 cm^2
25+10=35
So the area of the whole figure is 35 cm^2
Answer:
Angle A would be 40°
Step-by-step explanation:
The sum of all angles of a triangle is 180° always.
So, the sum of 80° , 11x - 4 and 15x would be 180°
80° + 11x - 4 + 15x = 180°
80 - 4 + 11x + 15x = 180°
76 + 26x = 180
26x = 104
x = 
x = 4
Since angle A is 11x - 4, its measure would be
(11 x 4) - 4
44 - 4
40.
16 + 8 is 25 and 34 - 24 is 10 so the value of x is 10.
