1. j + 150 x 50 is a(n) expression, because (1 point) numerical expression; it consists of only numbers
numerical expression; it consists of operation symbols
algebraic expression; it consists of numbers and a variable
algebraic expression; it has more than one operation symbol

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
