Answer:
x =19.2
y=29.8
Step-by-step explanation:
We will use the law of sines to solve this problem
sinA sin B
----------- = -------------
a b
sin 55 sin 40
--------- = ---------------
24.5 x
Using cross products
x sin 55 = 24.5 sin 40
Divide by sin 55
x = 24.5 sin 40 / sin 55
x =19.22512011
To one decimal place
x =19.2
To find the angle opposite y, we know the three angles of a triangle add to 180
y = (180-40-55) = 85
sin 55 sin 85
--------- = ---------------
24.5 y
Using cross products
y sin 55 = 24.5 sin 85
Divide by sin 55
y = 24.5 sin 85 / sin 55
y =29.79516474
To one decimal place
y=29.8
Answer:
Step-by-step explanation:
4(4) = -7(-3) - 5
16 = 21 - 5
16 = 16
answer is D
Answer:
-3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1, so replace the variables with the given values.
-5-5/1-x= -5/2, now multiply both sides by "1-x"
-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides
-20/2+5/2=5/2x, now simplify the equation
-15/2=5/2x, multiply both sides by 2/5
-30/10=x or x is -3
X greater than or equal to 5
5b +12c = 9
5b = 9 -12x
B= (9-12x)/5
