As we multiply the matrices on the left-hand side,we have;
x+3y=5---eq1
x+4y=6---eq2
eq1-eq2
-y=-1
y =1
Subsitution of y=1 in eq1,
x+3(1)=5
x+3=5
x=5-3
x=2
Answer:
arc AB = 12.40°
Step-by-step explanation:
diameter = 7.9 x 2 = 15.8
circumference = 15.8 x 3.14 = 49.612
since the central angle of arc AB is 90 °
90/360 x 49.612 = 12.40
60.7, 60.17, 60.1, 60.07, 60.007
