If there is a number before the decimal point. So one point five six (1.56) would be have a mixed number of one before the normal fractions ; 1 56/100
Answer:
Solution,
Here,∠FGD=∠CGE=30°[Being vertically opposite angles]
Now we have,
90°+∠CGE+x=180°
or,90°+30°+x=180°
0r,x=180°-30°-90°
→x=60°
Step-by-step explanation:
Answer: -1
Explanation: I'm not completely sure but I think you just have to substitute x with 1
Answer:
Part 1) The exact solutions are
and
Part 2) (1.79, 8.58)
Step-by-step explanation:
we have
----> equation A
----> equation B
we know that
When solving the system of equations by graphing, the solution of the system is the intersection points both graphs
<em>Find the exact solutions of the system</em>
equate equation A and equation B

The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
so
The solutions are
<em>Find the values of y</em>
<em>First solution</em>
For 


The first solution is the point
<em>Second solution</em>
For 


The second solution is the point
Round to the nearest hundredth
<em>First solution </em>

Answer:
x = 45
Step-by-step explanation:
Corresponding sides of similar triangles will be in same ratio.

Cross multiply
x*28 = 20*(x+18) {Use distributive method}
28x = 20x + 360
28x - 20x = 360
8x = 360
x = 360/8
x = 45
