Answer:
Step-by-step explanation:
Let the angles be 4x , 5x
4x + 5x = 180 { supplementary}
9x = 180
x = 180/9
x = 20
Larger angle= 5x = 5* 20 = 100
Answer: X=-1
Step-by-step explanation:
8-2i is their total score. You can't combine the imaginary numbers and real numbers.
Area = 0.5 x (a+b) x h
= 0.5 x (15cm + 6cm) x 1/5cm
= 0.1 x 21cm
=2.1cm^2 (2.1 centimeters squared)
Its 2.8, just multiply?<span />
