Answer:
blank A->(Law of cosines)
blank B->(Pythagorean theorem/theory)
Step-by-step explanation:
Reason to get the correct measurement's of angles in a figure you must apply Cosines or Law of Cosines(same thing) which simply means angle edges
and to get the measurements of the angles length use the Pythagorean theorem which is (a²+b²=c²)
- Hope I was helpful in any way thanks and sorry
Answer:If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion

IS THE SLOPE OF (2,5) (4,10)
Hi! Use the rule of three;
If 3cm---------50km
then 8.5 cm -------- x km
So;
(8.5 x 50 ) / 3 = 141.67
That means that it is 141.67 km aprox.
Answer:
24.3
Step-by-step explanation:
Because 1 is less than 5 so you round down
