Answer:
A.
Step-by-step explanation:
The third angle is 180 - 2*55 = 70 degrees.
So with 2 sides and 2 angles equal it is an acute isosceles triangle.
Answer:
A -19
B -35
C -180
D-9
Step-by-step explanation:
Answer: 13.4km/min
Step-by-step explanation:
Speed in km/minutes will be calculatedby rate divided by time= 114/8.5
=13.4km/min
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Two secants drawn from outside the circle, then
The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) ← distribute both sides
9 + 3y = 2 × 11
9 + 3y = 22 ( subtract 9 from both sides )
3y = 13 ( divide booth sides by 3 )
y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
The union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
<h3>What is a set?</h3>
A set is simply a mathematical model for a collection of different things which could be elements or members.
Union of sets represented with '∪' is the combination of two sets without repetition
Intersection of sets represented with '∩' is the sum of elements common between the.
From the expression given, we have;
[-9,-4] U (-4, 19)
= { -4, -9 , 19}
[-9,-4] U (-4, 19)
= { -4}
Thus, the union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
