Answer:
Acute
Step-by-step explanation:
7² + 9² ? 11²
49 + 81 ? 121
130 is greater than 121, so it is an acute triangle
Answer:
X = 2 / Z = 78
Explanation:
We are given 102 degrees, and the formula across from it, the one with the x, equals the same degrees. Knowing that we have to get them to equal each other, subtract 102-86, and you'll get 16. Next, divide 16 by the given number, 8, and you'll get x = 2
Knowing a straight line equals 180 degrees, subtract 180-102, and you'll get z, which is 78
Answer:
180
Step-by-step explanation:
450 x 0.4 = 180
Add 6+7+9, which gives 22.
Divide 44 by 22, which is 2.
Multiply the ratio by 2:
(6 : 7 : 9) * 2 = 12 : 14 : 18
The lengths of the sides are 12cm, 14cm, 18cm.
