Answer:
tan (C) = 2.05
Step-by-step explanation:
Given:
A right angled triangle CDE right angled at ∠D.
Side CD = 39
Side DE = 80
Side CE = 89
We know, from trigonometric ratios that, the tangent of any angle is equal to the ratio of the opposite side to the angle and the adjacent side of the angle.
Therefore, tangent of angle C is given as:
![\tan(\angle C)=\frac{DE}{CD}](https://tex.z-dn.net/?f=%5Ctan%28%5Cangle%20C%29%3D%5Cfrac%7BDE%7D%7BCD%7D)
Plug in the given values and solve for angle C.This gives,
![\tan(\angle C)=\frac{80}{39}\\\\\tan(\angle C)=2.051\approx 2.05(Rounded\ to\ nearest\ hundredth)](https://tex.z-dn.net/?f=%5Ctan%28%5Cangle%20C%29%3D%5Cfrac%7B80%7D%7B39%7D%5C%5C%5C%5C%5Ctan%28%5Cangle%20C%29%3D2.051%5Capprox%202.05%28Rounded%5C%20to%5C%20nearest%5C%20hundredth%29)
Therefore, the measure of tangent of angle C is 2.05.
Answer:
no figure 1 isn't similar to figure 2
Step-by-step explanation:
because its sides aren't the same numbers nor do the numbers correlate with the numbers in figure one its 2 different numbers
The value of the expression for the given values of a and b is -1
<h3>Evaluating an expression</h3>
From the question, we are to evaluate the given expression for the given values of a, b, and c
The given expression is
a + b
The given values are
a = 4,
b = -5,
and
c = -8
To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,
That is,
a + b becomes
4 + -5
= 4 -5
= -1
Hence, the value of the expression for the given values of a and b is -1
