Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm
Answer:
8
Step-by-step explanation:
1 2 3 <u>4</u> 5 6 7 <u>8</u>
8x8 + 15x15 = y^2
64+225 = 289
take the square root of 289 which = 17
ANSWER = C. 17
Answer:
Yes, it makes a<em> triangle.</em>
Step-by-step explanation:
When I used a measuring stick, it <em>does </em>create a triangle.
<span>Perhaps you mean that for any integers x and y, x > y, x² - y², 2xy, and x² + y² form a Pythagorean triple. If GCF(x, y) = 1, the triple is primitive.
For x = 5, y = 2, the triple is 21, 20, 29, or from smallest to largest,
20, 21, 29 âś
Let's just check
20² + 21² = 841= 29²</span>
