Problem A,B,C, and D can be solved using 3*6=18 or 6*3=18
Answer:
C
Step-by-step explanation:
Both triangles have three angles of the same value.
Remember that the angles in all triangles add up to 180°.
Let's use that to find out the unknown angles.
For the first triangle:
180 - 82 - 43 = 55°
55° is also in the second triangle.
Let's check with the second triangle:
180 - 82 - 55 = 43°
43° is also in the first triangle.
Therefore, both triangles are similar as the angles in both triangles are the same - 82°, 43° and 55°.
Hence, C.
Answer:
210
Step-by-step explanation:
GCF(30,42) = 6
LCM(30,42) = ( 30 × 42) / 6
LCM(30,42) = 1260 / 6
LCM(30,42) = 210

Step-by-step explanation:
Let's solve for y.
9x+6y=27
Step 1: Add -9x to both sides.
9x+6y+−9x=27+−9x
6y=−9x+27
Step 2: Divide both sides by 6.
6y
