Given
two angles (150° and 12°) and the shortest side (12 cm) of a triangle
Find
the second-shortest side
Solution
Strategy: Make use of the Law of Sines to find missing side lengths when angles are known. To find the third angle, make use of the sum of angles of a triangle.
The sum of angles of a triangle is 180°, so we have
... 150° + 12° + C = 180°
... C = 180° - 162° = 18°
The law of sines tells us
... c/sin(C) = b/sin(B)
... c = sin(C)·b/sin(B) = sin(18°)·(10 cm)/sin(12°)
... c ≈ 14.9 cm
_____
We are calling the sides a, b, c. We are calling the angles opposite those sides A, B, and C.
To make a congruent segment using a compass and a straight edge you need to get your compass and find the Distance between the two points, Then without changing the measurement copy it to a line. The straight edge would be used to make a line.
I hope this helps!
Answer:
3 3/8
Step-by-step explanation:
10 - 6 5/8 = 10 -(6 +5/8) = 10 -6 -5/8 = 4 -5/8 = 3 3/8
_____
Of course, you know that 5/8+3/8 = 1, so 1 -5/8 = 3/8.
Answer:
Explanation:
Given Total Numbers: 8 numbers
<u>Must be greater than 6</u>, The numbers are 7 and 8 = 2 numbers
Probability:
→ favorable outcomes/total possible outcomes
→ 2/8
→ 1/4
→ 0.25
Area of a rectangle = bh or lw
A = 27(9)
A = 243 feet
There are 3 feet in a yard
243/3 = 81
The flower bed is 81 square yards
