Answer:
The sign that makes the sentence true is an equal sign, =.
Yes, it could be converted into a fraction
Irrational numbers are number that cannot be written as a fraction
4083/1000
4 (83)/(1000)
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
Answer:
a or d) Other angle that could be in that isosceles triangle is 75°or 30°.
Step-by-step explanation:
Let us assume the given isosceles triangle is ABC.
Now, In an ISOSCELES TRIANGLE, two sides are equal.
⇒ AB = AC
CASE - 1 : Here: ∠A = 30°
Now,a s we know: ANGLES OPPOSITE TO EQUAL SIDES ARE EQUAL.
Now, as AB = AC
⇒ ∠B = ∠C = x
Now, by ANGLE SUM PROPERTY:
∠A + ∠B + ∠C = 180°
or, 30° + x + x = 180
or, 2 x = 150
or, x = 150/2 = 75
⇒ ∠B = ∠C = 75°
Case 2: ∠B = 30°
So, ∠C = 30°
Hence, other angles that could be in that isosceles triangle is 75° or 30°.
