Because not all sides are =
Answer:
Step-by-step explanation:
Exterior angle of a triangle is equal to the sum of opposite interior angles
13b - 48 = (9b - 47) + (b + 44)
Add the like terms
13b - 48 = 10b - 3
Add 48 to both the sides
13b - 48 +48 = 10b - 3 +48
13b = 10b + 45
Subtract 10b from both sides
13b - 10b = 10b + 45 - 10b
3b = 45
Divide both sides by 3
3b/3 = 45/3
b = 15
Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.
Hope this helps :)
The correct answer would be A as the mean is the average, mode is the most occurring number and median the middle number, all important aspects when comping a group of numbers.
Answer:
Both amplitude and coefficient are equal.
Step-by-step explanation:
Given the equation y = 50 sinx. we have to find the relationship between the amplitude of y = 50 sinx and the coefficient 50.
For the curve y = a sin x, the variable 'a' represents the amplitude of graph i.e
Amplitude=|a|
Hence, for the curve y = 50 sinx
Amplitude=|a|=|50|=50
which is equal to the coefficient 50.
Hence, both amplitude and coefficient are equal.
