Answer:
176°
Step-by-step explanation:
The total of exterior angles is 360°, so one of those for the regular polygon will be 360°/90 = 4°. The adjacent interior angle is the supplement of this.
The interior angles measure 180° -4° = 176°.
The answer to your question I believe is b
Answer:
x+3*1/x=52/7
7x^2/7x+21/7x=52x/7x
7x^2-52x+21=0
I solve this with the quadratic formula
Solution of ax^2+bx+c=0, a≠0 are :
x1= 
and x2= 
so a=7, b=-52,c=21
x1=
= (52+46)/14=98/14=7
x2=(52-46)/14=6/14=3/7

Answer:
Remainder is 425
Step-by-step explanation:
Let the two numbers Marsha has be A & B
From the question, we have the first equation as
A ÷ 70 = 64
Multiply both right and left sides by 70, we have:
A = 70 * 64 = 4,480
A = 4,480
From the question, we have the second equation as:
B ÷ 105 = 99
Multiply both left and right sides by 105, we have:
B = 105 * 99 = 10,395
B = 10,395
Remainder = (A + B) ÷ 35 = (4,480 + 10,395) ÷ 35
Remainder = 14,875 ÷ 35 = 425
Remainder = 425
Answer:
not finding the correct slope of the parallel and perpendicular line, forgetting to change an equation from standard form to slope-intercept form before finding the slope, and many more common mistakes
