Answer:
15:17
Step-by-step explanation:
Since the triangle has a right angle, we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side
CB is the hypotenuse side
and DC is the opposite side
Hence Sin B = 15/17
Answer:
percentages are used like fractions and decimals, as ways to describe parts of a whole. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are important for understanding the financial aspects of everyday life. When you are using percentages, the whole is considered to be made up of a hundred equal parts. The symbol % is used to show that a number is a percentage, and less commonly the abbreviation 'pct' may be used.
Answer:
The correct answer is B. 144
The measure of the fourth interior angle in the quadrilateral is 145
Answer:
+4.245
Step-by-step explanation:
Before you can find the square root of x^2, you have to EVALUATE
64+49-2(8)(7)cos32, and THEN take the square root of the result:
64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) = 113 - 94.981 = 18.019
Then x^2 = 18.019.
Find the square root of 18.019: It is +4.245. A negative result here would make no sense.
