Answer:
40 degrees
Step-by-step explanation:
If the angle is split into 2 angles, each measuring 20 degrees, then the original angle measures 20(2)=40 degress.
Answer:
y = 10/2x + 0
Step-by-step explanation:
Slope Int Form: y = m(slope)x + b(y-intercept)
The number before the x is the slope. To find the slope, count how far up or down and how far to the right or left. The b in the equation is the y-int so find the y-int of the graph.
= 4 1/2 (2 3/4 + 1 3/4)
Hope you give the brainliest answer.
Answer:
900 sq ft
Step-by-step explanation:
The area of a trapezoid is (Base 1 + Base 2) * height/2. So to plug the numbers in...
(30+60)20/2
90*20/2
1800/2
900 sq ft
Answer:
The distance between B and lighthouse is 3.8688 km
Step-by-step explanation:
Given:
The angle made from ship to lighthouse is 36.5 degrees
and that of point B is 73 degrees.
To Find:
Distance Between Point B and Lighthouse
Solution:
<em>Consider a triangle LAB(Refer the attachment )</em>
And Point C is on the line AB as A i.e. ship is sailing to B
So C is at 5 km from A.
Now In triangle LAC,
Using Trigonometry Functions as ,
tan(36.5)=LC/AC
LC=tan(36.5)*AC
=0.7399*5
=3.6998 km
Now In triangle LBC,
As,
Sin(73)=LC/LB
LB=LC/(Sin(73))
=3.6998/0.9563
=3.8688 km
LB=3.8688 km
