Answer:
160
Step-by-step explanation:
5x-10+12x=16x
17x-16x=10
x= 10
exterior angle at C = 16x= 16×10 = 160°
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
800 because 20*4*10=800 which means he works 80 weeks a month for 10 months
Answer:
184
Step-by-step explanation:
bottom rectangle area = 16 x 10 = 160
middle rectangle area= 3 x 4 = 12
Top triangle= 1/2(bh) = 8 x 3 = 24 (1/2) = 12
160+ 12 +12= 184
Answer:
60
Step-by-step explanation:
The computation of the rest of the marbles is given below:
Since there is 20 red and 15 white marbles
Also the 3 bags contains same marbles
So if he gives 45 marbles, so the remaining would be
= (20 + 15) × 3 - 45
= 35 × 3 - 45
= 105 - 45
= 60
