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}

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)

Therefore, the measure of tangent of angle C is 2.05.

galina1969 [7]

Answer:

The scale is not reasonable.

Step-by-step explanation:

The painting is 48 inches  by 120 inches

The scale is 1 inch = 4 inches

Divide the painting size by 4

48/4 = 12 inches

120/4 = 30 inches

We would need paper that is

12 inches by 30 inches

Our paper is 12 inches by 24 inches

It is too small.  The scale is not reasonable

What is the equation for <br><br> 6/7 - 1/8=
miv72 [106K]
Another way to put 6/7 - 1/8 is 48/56- 7/56 since the LCM of 7 and 8 is 56 (if you don’t know what that is I can explain it) sorta like subtraction you subtract both numerators (48 and 7 or 48-7) which gives you 41 then you put the denominator (56) below that. So in other words it equals 41/56
