Two y angles and the angle that is 35 degrees in total is 180 degrees, so we get the equation
y + y + 35 = 180
2y = 145
y = 72.5 degrees
Two y angles and a x angle is in total 180 degrees, so we get the equation
y + y + x = 180
2y + x = 180
2(72.5) + x = 180
x = 35 degrees
Hope that helps!
70-40= 30
30/2 = 15
40/2= 20
15 x 20 = 300
Answer: See explanation
Step-by-step explanation:
John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.
For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.
For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:
46.52 × 10 = 465.2
Answer:
4
Step-by-step explanation:
For this, you need to find the scale factor of two sides that are already given to you.
So, we will have to use the hypotenuse and one of the legs to make sure there is an accurate scale factor.
Hypotenuse:
15 / 5 = 3
Leg:
6 / 2 = 3
____________
So the scale factor is 3.
Using the leg (with the x) we need to divide 12 by the scale factor (3) to give us what x is equal to.
12 / 3 = 4
So, the answer is 4.
0.92 is the answer because you round the decimal 0.91666666666 to 0.92
