Answer:
61.15702689
Step-by-step explanation:
= 1 / 6 (49/9-14/3) + 27 / 73 / 5 × 33
= 1/6 x 7/9 + 61.02739726
= 61.15702689 = 61.16 (2 d.p.)
Answer:
<em>h = 8.54 units</em>
Step-by-step explanation:
<u>The Law of Cosines
</u>
It relates the length of the sides of a triangle with one of its internal angles.
Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:

Since we know the values of all three side lengths, we solve the equation for x:

For the triangle ABC in the image, a=10, b=15, c=13, thus:



Thus, A = 58.67°
For the right triangle of height h and hypotenuse 10, we use the sine ratio:

Solving for h:

h = 8.54 units
