you can subtract from point 1 to point 2
(9,-2) - (8,3)
9-8= 1
-2-3= -5
therefore horizontal leg is 1
vertical leg is -5
you can also sketch and count the units :)
I'm not sure what the rest mean, but the answer to question 1a is 15
Answer:
∠B = 22.5°, ∠C = 25.5°, c = 40.6
Step-by-step explanation:
an angle and 2 sides are given. It just so happens that the angle is across from one of the sides. Using the Law of Sines to find the missing angle B first.
36 sin(132) = 70 sinB and
and
sinB=0.3821887674
B=(0.3821887674)
B = 22.5
Now, find C using the Triangle Angle-Sum Theorem .
C = 180 - 132 - 22.5
C = 25.5 degrees
Using the Law of Sines again with angle A and side A and angle C:
and
c=40.6
It is the third option there. Locate the third B and that's where you solution starts.
Answer:
(3m - 2) + (2m + 7) + (5m - 3)
Step-by-step explanation:
Perimeter is found by combining all side measurements together to find the total measurement. In this case, combine the sides:
(3m - 2) + (2m + 7) + (5m - 3) is your answer.
If you need a simplified expression, simply combine all the like terms together. Like terms are terms with the same as well as same amount of variables:
(3m + 2m + 5m) + (7 - 2 - 3)
(10m) + (2)
10m + 2 is your answer.
