Answer:
B. 94
Step-by-step explanation:
Angle B = 180 - 143 = 37°.
Angle B + Angle C + Angle D = 180°
37° + 49° + Angle D = 180°
Angle D = 180° - 86° = 94°
(3,4) and (-5,6) are "coordinate planes".
These appear in algebra and math when you're graphing. These coordinate planes consist of "x" and "y" (x,y). The x's (which are 3 and -5 in your situation) should be graphed accordingly using the x-axis and the y's (which are 4 and 6 in your situation) should be graph accordingly using the y-axis.
Answer:
perimeter is length plus length width plus width
area is length times width
Step-by-step explanation:
(x+4)+(2x-23)=perimeter
(x+4)(2x-23)

1. Parenthesis:
(15)8 - 4 + 2 + 1
Multiply:
120 - 4 + 2 + 1
Subtract:
116 + 2 + 1
Add:
119, the answer is A.
2. 8 x 15 = 120
120 / 2 = 60
6 x 15 = 90
90 + 60 = 150
The answer is A.
Hope this helps!
