Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x =
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.
Answer:
0.2
Step-by-step explanation:
Given:
Total number of students = 20
Number of students who have brown hair = 12
Number of students who have blonde hair = 4
Number of students who have red hair = 3
Number of students who have black hair = 1
To find:
Probability of randomly selecting a blonde-haired student from the classroom.
Solution:
Probability refers to chances of occurring of some event.
Probability = Number of favourable outcomes/ Total number of outcomes
Number of favourable outcomes ( Number of students who have blonde hair ) = 4
Total number of outcomes = 20
So,
Probability of randomly selecting a blonde haired student from the classroom =
