Answer: x = 13; y = 13√2
because this is a right triangle, we have:
tan 45° = x/13
⇔ x/13 = 1
=> x = 13
we also have:
cos 45° = 13/y
⇔ 13/y = 1/√2
⇔ y = 13√2
Step-by-step explanation:
34* 68 = 2312 that is the answer
Answer:
d
Step-by-step explanation:
MK is the perpendicular bisector ò JL so MJL will be isosceles triangle, then JM = ML = 15, i guess
Answer:
x= -4
Step-by-step explanation:
Step 1: Simplify
2x-3+3x=-23 turns into
5x-3=-21 -- combined like terms
Step 2: Start Solving
5x-3 = -23
+3 +3 -- Getting x alone by adding 3 to cancel it out
5x = -20
/5 /5 -- getting x alone by dividing by 5 to again cancel it out
Step 3: The answer
x = -4
