Answer: D
Two sides are equal all angles smaller than. Right angle makes them acute
Step-by-step explanation:
Answer:
Angle 1, 2, 4 = 45 degrees
Step-by-step explanation:
2x+15 = x+30
-15 both sides
2x = x+15
-x both sides
x = 15
Plug x = 15 into x+30 or 2x+15
15+30 = 45
2(15)+15 = 45
Answer:
$17.45
Step-by-step explanation:

Answer:
0
Step-by-step explanation:
x2 +4x-21=0. solve for x


Answer:
x = 1.5
Step-by-step explanation:
Given


Required
Find the value of x.
First, the inequalities need to be rewritten and merged;
if
, then

Multiply both sides by 2


Similarly;

Multiply both sides by 2


Merging these results together; to give

This means that the range of values of x is from 1.5 to 4.9999....
From the question, x is the smallest rational number; from the range above (
), the minimum value of x is 1.5 and 1.5 is a rational number;
Hence, x = 1.5
