This doesn't make sense, as a triangle much equal 180, so it cannot have two angles bigger than 90, because this would mean it cannot be acute. A right triangle has one angle that is 90, obtuse as one that is bigger than 90 and two that are less, and an acute has three angles less than 90. Maybe there's a typo here?
Answer:
-1
Step-by-step explanation:
Area of triangle = 1/2 ABsinC
Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°
Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²
Answer:
slope should be 3

i used my calculator
Answer:
x=21/5, also known as 4.2
Step-by-step explanation:
5x:9 = 7:3
Solve it like a proportion and get any of these answers
5x/9 = 7/3
cross product property
3(5x) = 63
15x = 63
x = 63/15 = 21/5 in fraction form = 4.2 in decimal form
