Answer : 19
First, let our 19 be x
11+(19+6)=(11+ x)+6.
Then,
(11+x)+6=11+(19+6)
Now,
(11+x)+6: x+ 12.
Refined..
Remove parenthesis.(11+6x)+6 = 11 + x +6
Now, group like terms.
x+6+11
Add the numbers
=x + 17
Refined..
11+(19+6) : 36
x+ 17=36
Subtract 17 from both sides.
x+17-17=36-17
x= 19.
Hope this helps. :)

The right isosceles triangle PQR has vertices P(3, 3), Q(3, 1) and R(x, y) and is rotated 90 degrees counterclockwise about the

Jlenok [28]

For the answer to the question above, since the triangle is isosceles, the two legs have equal length. The coordinates of two vertices are given
P(3,3)
Q(3,1)
Assuming that PQ and QR are the legs of equal length, the distance between Q and R must be the same as the distance between P and Q
d = √[(3-3)² + (3-1)²
d = 2
Therefore, the coordinates of P is
(5,1)

Julia is standing 2 feet away from a lamppost. If she casts a shadow of 5 feet and the light makes a 20° angle relative to the g

givi [52]

Answer:

2.5477 feet

Step-by-step explanation:

Refer the image attached to understand my solution.

BC = height of lamppost.

DE = Julia

AD = shadow of Julia

BD = 2 feet. AD = 5 feet

BA = BD + AD

= 2 + 5 = 7 feet

In ΔABC

tan 20° = $\frac{BC}{BA} = \frac{BC}{7}$

BC = 7 * tan 20°

BC = 2.5477 feet

SO the height of lamppost = 2.5477 feet
