Two angles are complementary. they also have the same measure. which statement is correct? a the two angles must be adjacent. b the two angles are obtuse. c the two angles cannot be adjacent. d the two angles are acute.

d. The two angles are acute.

Step-by-step explanation:

Complementary Angles sum up to 90.° Since they both have the same measure, take half of 90° to get two exact same measures of 45°. Now, if you have noticed, you can tell that 45° is considered acute because it is less than a ninety-degree right angle:

180° → Straight Angle

Less than 180°, but greater than 90° → Obtuse Angle

Less than 90°, but greater than 0° → Acute Angle

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
