Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2x² - x + 5
f(-3) = 2(-3)² - (-3) + 5
= 2(9) + 3 + 5
= 18 + 3 + 5
= 26
Use Law of Cosines g^2 = f^2 + h^2 -2fhCosG f^2 = g^2 + h^2 -2ghCosF h^2 = f^2 + g^2 -2fgCosH
f^2 = 28^2 + 15^2 -2*28*15Cos87 28^2 = 31^2 + 15^2 -2*31*15CosG
f^2 = 784 + 225 - 43.96 784 = 961+225 - 930CosG
f^2 = 965.0378 784 - 1186 = -930CosG
f = 31 -402 = -930CosG Divide by -930
.432258 = CosG
Cos^-1(.432258) = G
G = 64 degrees
Angle H = 180 - 64 - 87 = 29 degrees
Side f = 31 Angle F = 87 degrees
Side g = 28 Angle G = 64 degrees
Side h = 15 Angle H =29 degrees
Answer:
its B, A, C
Step-by-step explanation:
correct on edge
First find the unit rate. 230 divided by 10 which is 23 bagels per hour. So now multiply 23x24 which equals 552 bagels in 24 hours.
Answer:
1). angle 3= 48° [by vertically opposite angle]
2). angle 4 = 132° [by linear pair]
3). angle 5 = 50° [angle 6 and angle 5 are complementary angles]
4). angle 8 =36° [angle 7 and angle 8 are complementary angles]
5). angle 6 = 31° [sum of angle on straight line is 180°]
6). angle 8=33° [sum of angles on straight line is 180°]
7). angle 9=40° [sum of angles of triangle is 180°]
8). angle 3= 30°[angle 9 and 12 are linear pair and 9 is part of the triangle. so, sum of all angle of triangle is 180° ]
9). angle 15= 80° [sum of angles of triangle is 180°]
10). angle 8=35° [sum of angles of triangle is 180°]
11). angle 7=66°[sum of angles of triangle is 180°]
12). angle 14=105° [Sum of angles of triangle is 180°]
13). angle 12=130°[by sum of angle is 180°we'll find 9 then by linear pair angle 12= 130°]
14). angle 8=55° [ angle 14 and 16 are equal by vertically opposite angles and angle 14+angle 8+angle 3=180°]
15). angle 15=90°[first find 7 and 9 by sum of 90°and sum 180° then sum of angles of triangle is180°]
16). angle 16=95°[angle 7 and 8 are complementary angles and angle 1 and 3 are equal by vertically opposite angles now we have our two angles of the triangle so we can find third angle because sum of angle of triangle is 180°]
