Answer:
(d) 2
Step-by-step explanation:
C²=a²+b²-2·a·b·cos(C)
c²=(1.5)² + (0.5) -2 ·(l·5) ·(0.5) ·cos(120°)
c²= 3.25
c= √3.25
c=1.802775638
To nearest tenth, c=1.8
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right. This is done in the example below. Each decimal in Example 1 went out two places to the right of the decimal point.
YOU CAN DO THIS ONE OF 1 OF 2 WAYS....
650 X .48= 312
650 X .44=286
312+286=598
650-598=52
OR FIGURE IT THIS WAY
.48+.44=.92
650 x .92= 598
650-598=52
