Let "a", "b" and "с" be sides of the triangle ("с" is the longest side).
The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
a.
a=3, b=4 and c=5
a² + b² = 3² + 4² = 9 + 16 = 25 and c² = 5² = 25
25 = 25 ⇒ right triangle.
b.
a=5, b=6 and c=7
a² + b² = 5² + 6² = 25 + 36 = 61 and c² = 7² = 49
61 > 49 ⇒ аcute triangle.
c.
a=8, b=9 and c=12
a² + b² = 8² + 9² = 64 + 81 = 145 and c² = 12² = 144
145 > 144 ⇒ аcute triangle.
Answer:
X = 63°
W = 60°
Y = 57°
Step-by-step explanation:
W = X - 3
Y = X - 6
X + W + Y = 180 substitute
X + (X - 3) + ( X - 6) = 3 X - 9 = 180
3X = 189
X = 63
W = 60
Y = 57
Answer:
False
Step-by-step explanation:
Simple interest is the percentage rate that a borrower pays to borrow money for a set period of time, whereas compound interest is calculated on top of what has already been borrowed, which means that as time passes, more and more interest charges accumulate until repayment begins. e. when a borrower pays interest on the principal plus interest charges that have accrued.
(5x6) x 2 = 60 I am so sorry if it’s not correct I’m not on my best game today
