BrainiestI WILL GIVE BRAINLIEST look at the right angled triangle abc
marissa [1.9K]

Answer:

x = 90°

y = 40°

z = 40°

Explanation (Concepts) :

A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

Workouts:

z + 90° + 50° = 180°

z = 180° - 90° - 50°

z = 40°

=================

x + 90° = 180°

x = 180° - 90°

x = 90°

==================

50° + 90° + y = 180°

y = 180° - 90° - 50°

y = 40°

Can someone help me please​

Answer:

7/10

Step-by-step explanation:

I've attached an image on how you can use the diagram they gave you.

If you color in 7/10s and 7/12s you'll notice that 7/10s is greater.

This is because 1/10 of the whole is greater than 1/12 of the whole.

For 1/10, the whole is being divided into 10, so it equals 0.1.

On the other hand, in 1/12, the whole is being divided by 12, so a part equals 0.083

0.1 is greater than 0.083, so 7 of 0.1 is greater than 7 of 0.083

Answer:  

Year 10 Interactive Maths - Second Edition

Problem Solving

Linear equations are often used to solve practical problems that have an unknown quantity. We use a suitable pronumeral to represent the unknown quantity, translate the information given in the problem into an equation, and then solve the equation using the skills acquired earlier in this chapter.

Example 11

If a number is increased by 8, the result is 25. Find the number.

Solution:

Let x be the number.  Increasing x by 8 gives x + 8, which we are told is 25.  Therefore, x + 8 = 25.  Subtract 8 from both sides to find x = 17.  So, the number is 17.

Step-by-step explanation:
