Answer:
.79
Step-by-step explanation:
You multiply 1.89×2 to get 3.18. Then you subtract 3.78 by 2.99 and get .79
Answer:
<A=56.64
<B=114.99
<C=8.33
Step-by-step explanation:
let angle C be x
8x-10+3x+90+x=180°[sum of inside the triangle is 180°]
12x+80=180
12x=180-80
x=100/12
x=8.33
now putting the value of x
angle C is 8.33
angle A is 56.64
angle B is 114.99
Answer:
(8,-1)
Step-by-step explanation:
Given :
To Find: solution of given system of equations.
Solution:
Equation a :
Equation b :
Substitute the value of y from equation b in equation a
y from equation b : y = 7-x
Now substitute value of y in equation a
Thus equation a becomes:
⇒ x= -1 and x = 8
Now substitute values of x in equation b to obtains values of y
⇒
for x = -1
⇒
⇒
⇒
Thus (x,y)=(-1,8)
For x =8
⇒
⇒
⇒
Thus (x,y)=(8,-1)
Hence Option A is the correct solution .
