Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle = 
, where p is half the perimeter of the triangle
p = 
units
Area = 
= 62.1467 square units (correct to four decimal places)
The solution is this :) Hope you understand my handwriting
The interest is $77.60 i think
Answer:
f(-10)=53
Step-by-step explanation:
Let
f(x)=
+5x+3.............(1)
we have to find
f(-10)=?
for this we will put x=-10 in equation (1)
f(-10)=
+5(-10)+3
f(-10)=100-50+3
f(-10)=53
Answer:
the value of X is 122
Step-by-step explanation:
First, all triangle angles add up to 180 so to find the missing angle we subtract 51 and 71 from 180 and get 58
Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x
