Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
8 Females have to leave the room which then it would be 22 males and 22 females which is a 1-1 ratio
Sorry i am late to the party but the snawer for the first problem is SAS. We know that segment AD is congruent to segment CD becausse of those tick marks. We also know that the angles towards the bottom of the diagram are congruent because they have the angle symbols. Finally BD=BD because of the reflexive property. We have a side an equal angle and finally another side.
Number 2 is SSS. Segment PR is congruent to Segment NQ because of the tick marks (1 line of tick marks.) In addition, PN=RQ because they both have 2 tick marks. Lastly we know PQ=PQ because of the reflexive property. We have a side, a side, and another side.
The answer is 49,152.
You double the numbers as you go, it goes up to 49,152.
