Answer:
15 degrees, 75 degrees
Step-by-step explanation:
Call the first angle's measurement m
∠
1
.
The second angle is 5 times this, or 5
(
m
∠
1
)
.
Since the two angles are complementary (have a sum of 90
˚
), we can relate the two angles him as follows:
m
∠
1
+
5
(
m
∠
1
)
=
90
6
(
m
∠
1
)
=
90
m
∠
1
=
15
Since m
∠
2
is 5
times this, m
∠
2
=
15
×
5
=
75
.
I'M NOT TO SURE ABOUT THIS ANSWER BUT I HOPE THIS CAN HELP SOME PEOPLE.
The information given is sufficient for this proof .
Slope of a line passing through x1 ,y1) and ( x2,y2) is given by the formula :
M = ( y2 - y1)/ ( x2-x1)
________________________________
Let us start finding the slope of line PQ
the given points are ( a,b) and ( c,d)
using the slope formula we get :
slope of line PQ = m= ( d-b) /( c-a)
Let us now try finidng slope of the another line P'Q'
It is passing through ( -b ,a) and (-d,c)
using the formula we get slope of P'Q' = m' = ( c-a) /( -d - -b)
m'= ( c-a) /( -d+b)
m'= ( c-a) / -( b-d Let us find the product of m and m' :
( d-b ) * ( c-a)
----------- ------------ = -1
(c-a) - ( b-d)
Because we got product of m and m' = -1 hence proved product of perpendicular lines are negative reciprocal of each other .
In order to get the total price, we can multiply the 4 dollars by .05 to find 5 percent of the object's cost and add it to the sales tax. So, .05 times 4 is 0.2, meaning there is a sales tax of 0.2 dollars. We add that to the four, so the total price is 4.20 dollars. Hope this helps.
