Answer:
Sin A = 15 / 17
Step-by-step explanation:
Given a right angled triangle, we are to obtain the Sin of the angle A ;
Using trigonometry, the sin of the angle A, Sin A is the ratio of the angle opposite A to the hypotenus of the right angle triangle.
Hence. Sin A = opposite / hypotenus
Opposite = 15 ; hypotenus = 17
Sin A = 15 / 17
The inequality would be 34 > 2 x 3, if I'm correct. I'm not to sure on the graph part though , sorry.
Answer:
128 men
Step-by-step explanation:
90 × 28 × 8 = M × 18 × 15/2
M = 128
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=<u>O</u>pposite over <u>H</u>ypotenuse
Cos=<u>A</u>djacent over <u>H</u>ypotenuse
Tan=<u>O</u>pposite over <u>A</u>djacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be 
and cos A (adjacent over hypotenuse) would be 
.
I hope this helps!
Answer:
Surface area of pyramid = 1536 square inches.
Step-by-step explanation:
Surface area of a pyramid with the square base will be = surface area of base + 4× slant surfaces of the pyramid
area of square base = 24×24 = 576 inches²
area of one slant side of pyramid = (1/2)×side × slant height = (24×20)/2 = 240 square inches
Therefore surface area of complete pyramid = 4×area of slant side + surface area of square base = 4×240 + 576 = 960 + 576 = 1536 square inch.
