An object's dimensions are: length of 25cm, wight of 10cm, and height of 15cm. calculate the object's density if its mass is 3000g
Answer:
SMA= 24 degrees
Step-by-step explanation:
add the other given angles together: 66 + 90= 156
subtract 158 from 180 (every triangle has a total of 180 degrees): 180-156 = 24
First, change this equation to y-intercept form:
-4x+7=2y-3
2y = -4x+10
y= -2x + 5
The slope is -2, which is the coefficient for x in y-intercept form.
x is 14.3

the right angle is 90 degrees, so sin(a) is 90

multiply sin(90) on both sides to give:

x is 14.3
