Answer:
Step-by-step explanation:
7x+5=7x+5
-7x. -7x
Answer is 5=5
is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)
(or 30 degrees)
sin
3/4 - 1/5
0.75 - 0.2
0.55
Answer: 0.55 or 11/20
Answer:
-x² + 8x - 7
Step-by-step explanation:
Step 1: Write expression
(7 - x)(x - 1)
Step 2: FOIL (First Outside Inside Last)
7x - 7 - x² + x
Step 3: Combine like terms
-x² + 8x - 7
Answer:
<A=143
Step-by-step explanation:
<A=<B (corresponding angles)
7x+24=3x+92
7x-3x=92-24
4x=68
dividing both sides by 4
x=17
Now <A=7x+24
<A=7(17)+24
<A=119+24
<A=143
