<em>*Remember that A = angle and S = side.</em>
So remember that <u>similar figures have congruent angles and proportional sides.</u> Looking at triangles ABC and DEF, they both share 85° and 30° angles. <u>With this, the two triangles are similar by AA, or the first option.</u>
Answer:
Step-by-step explanation:
c + f = 16......c = 16 - f
340c + 910f = 9430
340(16 - f) + 910f = 9430
5440 - 340f + 910f = 9430
-340f + 910f = 9430 - 5440
570f = 3990
f = 3990/570
f = 7 <====== 7 first class tickets bought
c + f = 16
c + 7 = 16
c = 16 - 7
c = 9 <====== 9 coach tickets bought
Answer:
its 6.40
Step-by-step explanation:
you have to use the distance formula which is

so points C is (-5,-1) and D is (0,3)
then you substitute the x
0--5=5^2
then
3--1+4^2=16
25+16=41
then square rout that and it equals 6.40
Answer:
2: The perimeter of the base is 37 units.
Step-by-step explanation:
1. A = LW = 21 * 16 = 336 units^2 True
2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units False
3. H = 21 units True
4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2 True
