Answer:
x = 60°
Step-by-step explanation:
We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.
x + 30 + 90 = 180
x + 120 = 180
x = 60
Therefore, it is 60°.
Answer:
490
Step-by-step explanation:
The fraction that represents the addition model shown above will be 53/100.
<h3>How to solve the fraction?</h3>
From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.
Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.
Therefore, the problem that represents the addition model shown above will be:
= 5/10 + 3/100
= 50/100 + 3/100
= 53/100
In this case, the answer given by Emma is incorrect as he added 5 to 3 and got 8/100.
