Complementary angles have measures (4x)° and (5x−27)°. find the measure of the larger angle.
Luda [366]

Answer:

4x=90

X=90÷4

X=22.5

5x-27=90

5x=90+27

5x=117

X=117÷5

X=23.4

So 23.4 is a larger angle

What is DE ?<br><br> Enter your answer as a decimal in the box.<br><br><br> ____ units
Fantom [35]
<span>6.3 Looking at the triangle, you can see that point D bisects line segment AB and that point E bisects line segment BC. In fact, you can easily determine that triangles ABC and DBE are similar triangles with DBE having sides that are half the length of the respective sides in ABC. And since line segment DE corresponds to line segment AC which is 12.6 units long, line segment DE is 12.6/2 = 6.3 units long.</span>

Select all the ratios equivalent to 8:6.<br><br>A. 4:3<br>B. 6:8<br>C. 16:12<br>D. 10:8<br>E. 7:5​
omeli [17]

9514 1404 393

Answer:

  A, C

Step-by-step explanation:

The given ratio can be reduced by removing a factor of 2 from each element.

  8 : 6 = 4 : 3 . . . . matches A

It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...

  8 : 6 = 16 : 12 . . matches C

__

Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.
