What can you be more specific like a put it in a sentence. For example x*-260+7=?
Answer:
15
Step-by-step explanation:
If the other triangle is part of the problem the triangle increased by 2.5
2.5 * 6 is 15
so 15 is the length of TR
Let the angle be x
complement 90-x
so the equation will be
3x = 90-x-14
3x+x = 90-14
4x = 76
x=76/4= 19
90-x= 90-19 =71
V•w = (-7i +4j)•(-6i +5j) = (-7)×(-6) +4×5 = 42 +20
v•w = 62
