Answer:
1. X=35 degrees obtuse
2 x=25 degrees right
Step-by-step explanation:
Background info:
The measures of the angels of every triangle is 180 degrees
So x equals 180 minus the other angles combined
1. X=180-(40+105)
X=180-145
X=35 degrees
2.
x=180-(90+65)
x=180-155
x=25 degrees
This is the concept of perimeter of geometric figures;
We are required to approximate the perimeter of the triangle given if JA=10, AL=23, CK=9
Summing the above measures we get;
10+23+9=42
assuming that this is half the perimeter of the whole triangle then;
perimeter=2*42=84
The answer is A
Answer:
t= -1
Step-by-step explanation:
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
cross multiply:
1(t -6)= 7(-1)
t -6= -7
+6 on both sides:
t= -7 +6
t= -1
The answer is a : y - values
