Sonji has $5.25 in nickels and dimes . The coin value can modeled by the equation 0.10+0.05n=5.25, where d represents the number

of dimes and n represents the number of nickels . If sonji has 21 dimes, how many nickels does she have ?

.10d + .05n = 5.25

.10(21) + .05n = 5.25

2.1 + .05n = 5.25

.05n = 3.15

n = 3.15/.05

n = 63

The sum of the three angles of a triangle is 180°. Two angles of a triangle measure 15 and 73. Of x is the third angle, set up a
Agata [3.3K]

Answer:

The measure of the third angle is 92°

Step-by-step explanation:

We first have to make an equation that represents this equality. To do it we simply have to add the values ​​that give us with x and this will result in 180 °

15° + 73° + x = 180°

once we have the equation what we have to do is solve x, so we will pass all the terms that are adding to x by subtracting 180

x = 180° - 73° - 15°

now that we have cleared the x we ​​only have to perform the indicated operation and we will obtain the value of x

x = 92°

The measure of the third angle is 92°

Find the measure of ZDCF. C F mDF = 49 G E MEG = 127 Find the measure of angle DCF​
AleksandrR [38]

Answer:

Step-by-step explanation:

Comment

If two secants intersect outside a circle (as these two do) then the angle at which they meet is 1/2 the difference between the intersected arcs. Put much simpler <DCF = 1/2 (arc EG - arc DF)

Givens

Arc EG = 127

Arc DF = 49

Solution

<DCF = 1/2(127 - 49)

<DCF = 1/2(78)

<DCF = 39
