Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
y + 3y + y + 30 + 90 = 360 , that is
5y + 120 = 360 ( subtract 120 from both sides )
5y = 240 ( divide both sides by 5 )
y = 48
3y = 3 × 48 = 144
y + 30 = 48 + 30 = 78
The measure of the 4 angles are
48°, 78° , 90° , 144°
2 2/3 inches cubed
volume is length x width x height. 3 x 2 2/3 x 1/3 = 2 2/3.
A. DEF where and .
At first we must keep in mind that two triangles are similar when they have same angle configuration, that is, each pair of angles is congruent. If ABC and DEF, then and . Hence, and .
In a nutshell, correct answer is A.
is this homewwork or a test?
the difference between is 4/12 witch could be divided to 1/3
