Answer:
12 students
Step-by-step explanation:
1. 7s+16=100
We know the teacher has 100 markers, and she gave each student 7. If we say that s is the number of students, then 7s is the number of markers she gave out. We also know that she had 16 left over.
2. 7s+16-16=100-16
Subtract 16 from both sides of the equation.
3. 7s=84
Simplify the equation.
4. 7s/7=84/7
Divide both sides by 7.
5. Simplify the equation. Since s is the number of students, we now know how many students there are in the teacher's class.
Answer:
Make a triangle with an opposite side of 4 and adjacent side of 3 (hypotenuse is 5). You can now work out all trig functions for that angle. including sin(x)
Use the double angle formula to find sin(2x)
Step-by-step explanation:
If you subtract 13- -19, you get 32 degrees
Answer:- B , C and F are the right options.
Explanation:-
1. HA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
2. HL can be a reason to show given triangles are congruent as the triangles are right triangle with equal legs and hypotenuse.
3. SAS can be a reason to show given triangles are congruent as there are two congruent sides in both triangles and included angles ∠A=∠D=90° [right angle].
4. LA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
5. AAS cannot be a reason to show given triangles are congruent as it is not given that they have two angles common in both the triangles.
6.SSS can be a reason to show given triangles are congruent as it is shown that all the sides of one triangle is congruent to the other.
