Answer:

Top question: -7°

Bottom question : 18°

Step-by-step explanation:

Top question:

The base angles of am isosceles triangle are congruent:

x + 46 = 39 because the base angles of an isosceles triangle are congruent

x + 46° = 39°

x = -7°

Bottom question

The missing angle is 3x because the base angles are congruent

To find the value of x, we must add all the angles inside the triangle, and find the value of x that makes it equal to 180°

3x + 3x + 4x = 180°

10x = 180°

x = 18°

Sorry for the late post!

A pitcher can hold 5. 2 liters of water. How many 0. 4 liter glasses of water can be poured from the pitcher?
gogolik [260]

The number of 0.4 liter glasses of water that will be poured in the pitcher is 13

From the information given, we are being told that a pitcher can hold a maximum amount of 5.2 liters of water.

If we are to use a 0.4 liter of glass to pour water in the pitcher, then the number of times we will use the glass to pour water in the pitcher can be estimated as:

Number of glass that can fill the pitcher = 5.2 liters/ 0.4 liters

= 13 glass
