Answer:
<em>x = 9</em>
<em>y = 36</em>
Step-by-step explanation:
<u>Lines and Angles</u>
Triangle CDE is isosceles. This means the two angles of the base DE are congruent (have the same measure):
7x + 1 = 4x + 28
Subtracting 4x + 1:
3x = 27
Dividing by 3:
x = 9
Substituting in the expression for the angles:
7x + 1 = 7*9 + 1 = 64°
The angles are 64° and 64°. The other internal angle at vertex C is 180°-64°-64°=52°. This angle is congruent with its vertical angle in the triangle ABC. We are given another angle of 43°. Thus the measure of angle A is 180°-52°-43°=85°
This last angle is equal to the expression of y:
-2(3 - y) + 19 = 85
Subtracting 19:
-2(3 - y) = 66
Removing the parentheses:
-6 + 2y = 66
Adding 6:
2y = 72
Dividing by 2:
y = 36
Final answer:
x = 9
y = 36
Answer:
23.7 miles or 24 miles rounded
Step-by-step explanation:
To do this, you only need to know the conversion of inch to mile. In this case, 1 inch equals 1.58x10^-5 miles, so:
1.5x10^6 inches * 1.58x10^-5 miles/inch = 23.7 miles
Now, as you want it to the nearest hundredth, the answer is simply 24 miles
No thats only if your multiplying it gets confusing like that
Yes, she is absolutely correct because 32/4=8
8>4 so it make sense.
2(pi)r...(2)3.14(4.5)= 28.26 so, false
