Answer:
what do you want help with
There's no such thing as the "length"of an angle.
But we know what you're getting at.
You have said that the angles are complementary. If two angles are
complementary, then their sum is 90 degrees, so we can take your
two angles and write:
<u>x</u> (one angle) plus <u>(2x + 12)</u> (the other one) <u>= 90 degrees
</u><u /> x + 2x + 12 = 90<u>
</u>Subtract 12 from each side: x + 2x = 78
Add the x's on the left side: 3x = 78
Divide each side by 3 : x = 26 degrees
One angle is 'x' = <em>26 degrees</em>
The other one is (2x + 12) = 52+12 = <em>64 degrees</em>
Hello! The $74 is the one-time price paid for the car, and there is a charge of $1.50 per mile. Isabella paid $95.60 to rent a convertible for 1 day. We can write and solve an equation to solve for the number of miles she drove. Set it up like this:
74 + 1.50m = 95.60
First off, subtract 74 from both sides in order to get 1.50m = 21.6. Now, divide each side by 1.50 to isolate the "m". 21.6/1.5 is 14.4. We can solve in reverse to make sure this is the right answer. 14.4 * 1.5 is 21.6. 21.6 + 74 is 95.6. 95.6 = 95.60. There m = 14.4. Isabella drove 14.4 miles.
Answer:
1) True 2) True 3) False 4) True
Step-by-step explanation:
In this question let's verify those options
1.Triangle A B C is inside triangle D E F. (true)
If A, B and C are midpoints of DEF then connecting those midpoints we have an interior triangle.
2. Point A is the midpoint of side F D, point B is the midpoint of side D E, point C is the midpoint of side F E. (true)
3. Angles D F E and A B C are right angles. (false)
These triangles are similar. And In this case, the right angles are:
D and C are opposed to the larger side, and not F, and B
Because:
4. The length of D E is 10 centimeters, the length of F D is 6 centimeters, and the length of F E is 8 centimeters. (true)
Let's test this by the Pythagorean Theorem. For DE is the hypotenuse and FD and FE is their legs.
