Answer:
j=1.571
Step-by-step explanation:
to get j by itself you have to divide 7 by 11
so,
11/7=j
j=1.571
Two ways of solving it:
The angle beside the 71 is equal to
180 - 71 = 109
so a triangle angles sums up to 180
so the reminaing is
x = 180 - 109 - 28 = 43
solution (2):
the exterior angle = sum of interior angles except the one near it.
28 + x = 71
x = 43
Answer:
Your answer is correct... it's no.3 ... but if you multiply a inequality by a negative value the inequality sign changes.. like if you habe greater than it'll be less than... Keep that in mind too
Answer:
7.7
Step-by-step explanation:
The area of the wall is 4 * 2 = 8.
The radius of each clock is 0.3 / 2 = 0.15.
The area of all 4 circles is 4 * (πr²) = 4 * 3.14 * 0.15² = 0.3.
8 - 0.3 = 7.7
