Answer:

$\angle CFD =105^o$

Step-by-step explanation:

Given

$\angle D FE = \angle DE F = 75^o$

See attachment

Required

Determine the measure of $\angle CFD$

$\angle CFD$ and $\angle DFE$ are on a straight line.

So:

$\angle CFD + \angle DFE = 180^o$ --- angle on a straight line

Substitute known values

$\angle CFD + 75^o = 180^o$

Collect like terms

$\angle CFD =- 75^o + 180^o$

$\angle CFD =105^o$

vlada-n [284]

Answer:

$ 79600

Step-by-step explanation:

interest=prt (p is the amount borrowed, r is the rate, t is the time)

p=60000 , r=8%=0.08 , t=4 years

interest=60000*0.08*4

A=19600

the amount paid at the end of 4 years: 60000+19600=$79600

What is the probability that a 13-card bridge hand contains all cards from the same suit?

slega [8]

The total number of 13-card hands that can be dealt is 52C13. Four of these are of the same suit. Therefore the required probability is given by:
$\frac{4}{52C13}= 6.3\times 10^{-12}$
