The size of the 4th angle is 72.
Given:
1st angle = 148
2nd angle = 104
3rd angle = 36
shape = quadrilateral.
A quadrilateral is a shape that has 4 sides or edges, 4 corners or vertices.
It goes to show that it must also have 4 angles. These four angles must give the sum of 360°.
Since the first three angles are given, we can get the fourth angle by deducting the sum of the three angles from 360°
4th angle = 360° - 148° - 104° - 36°
= 360° - 288°
4th angle = 72°
Answer:
<h2>£1346.97</h2>
Step-by-step explanation:
Step one
given the amount £761
we are asked to increase this amount by 77%
let us first find 77% of the amount £761
=77/100*761
=0.77*761
= £585.97
Step two:
Hence 77% of £761 is £585.97
therefore the increase will be to add the two amounts together
=£585.97+£761
=£1346.97
<h3>
Answer: (x+7)^2 + (y+2)^2 = 4</h3>
===========================================================
Explanation:
The center is at (h,k) = (-7,-2)
h = -7
k = -2
The radius is r = 2 units
Plug these three pieces of info into the template below and simplify
(x-h)^2 + (y-k)^2 = r^2
(x-(-7))^2 + (y-(-2))^2 = (2)^2
(x+7)^2 + (y+2)^2 = 4
You can use a tool like Desmos or GeoGebra to confirm the answer.
