II. Triangle ABC is obtuse and III. Triangle ABC is acute, because acute is less than 180° and obtuse is between 180° and 270°
Answer:
9/8
Step-by-step explanation:
add - 1/2 to both sides giving you p
but to you need to find like terms so
times 1/2 by 4
4/8 + 5/8 = 9/8
Answer:
s=-1

13+8s-6=-1
7+8s=-1
-7
8s=-8/8
Answer:
x² - 8x + 16 Hope this helps
Step-by-step explanation:
Step 1: Write out expression
(x - 4)²
Step 2: Expand
(x - 4)(x - 4)
Step 3: FOIL
x² - 4x - 4x + 16
Step 4: Combine like terms
x² - 8x + 16
Answer:
∠W = 16.3°
Step-by-step explanation:
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°
