We know that the summation of angles of a triangle is 180<span>°. Then we find angle of C by,
</span>m∠A + m∠B + m∠C=180°
80° + 50° + m∠C=180°
m∠C=180°- 80°+ 50°
m∠C=50°
Since we now angle of C, we can use Sine Law in solving for AC
sinC/AB=sinB/AC
sin50°/6 =sin50°/AC
AC=6cm
Therefore, AC is equal to 6cm.
The volume of a cylinder is 3 times larger than a cylinder. So find your answer for the cylinder and multiply it by 1/3 to get your answer. Hope this helps! Study on!
Answer:
i cant see the answers what do they say?
Step-by-step explanation:
Slope of line j;
m=
m=
m=
Parallel lines have equal gradients;
So,
y=mx+c
y=5/3x+c
Replacing for x and y;
-1=5/3(15)+c
-1=25+c
c=-26
y=
-3 3/4
Decimal form: -3.75
