Answer: 40 degrees
Step-by-step explanation:
180-140=40
Answer:
Step-by-step explanation:
It's helpful to draw it out, but you need a calculator for this.
You have the values of line b, line c, and angle C.
You can use sinC / c since you have C and c.
Solve for sinB by doing sinB/5.7 = sinC/8.6
you'll get the value of sinB, use inverse trig to solve for B (sin^-1)
Then you'll have the angle values for C and B. Add them, and subtract by 180 to find the angle measure of A.
Use the steps above to find a:
sinA (which u just found) / a = sinC (125) / c (8.6)
Hope this helps.
Answer:
The slope which is 3
Step-by-step explanation:
Slope intercept is y=mx+b where b is the y-intercept and m is the slope.
To find the slope subtract the y values and divide it by the difference of x values.
y2-y1=-1--7=-1+7=6
x2-x1=2-0=2
6/2=3
