What is the length of line segment BC?
1 answer:
Answer:
d. 10.53 units
Step-by-step explanation:
This question could be answered by Pythagoras Theorem which is :
In every triangle c is always the hypotenuse ( which is the longest line in the triangle/ the line where the right angle sign is pointing to )
a or b could be either one of the other lines of the triangle it doesn't matter.
First you find AC which is simply by adding the two 5.2 values which is 10.4 units.
BC can be written as b in our Pythagoras equation and if you first substitute it you will have:
To find b you rearrange everything to the other side except b
And if you type that in the calculator you get
BC= 10.53 units (2 decimal place)
Hope it is right, and ask any questions if unsure :)))

The steps to find cos, sin, and tan and missing adjacent side of a given right angle triangle is explained.
<u>Solution:</u>
Given, a right triangle with A, B, and C.
Opposite side = 70 inches
Hypotenuse = 12 feet = 12 12 inches = 144 inches
Adjacent side = "x" inches.
We are not given angle, so we have to use the hypotenuse theorem
Hypotenuse theorem means square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
Substituting the values we get,
So, the adjacent side value is 125.8 inches approximately.
Hence the steps to find adjacent side is shown above
Now let us find cos, sin and tan
By substituting the required values, we can find cos, sin and tan
