Answer:

<h2>107 mm²</h2>

Step-by-step explanation:

The formula of an area of a rectangle:

A=l\cdot w

<em>l</em><em> - length</em>

<em>w</em><em> - width</em>

<em />

The area of ​​a given shaded region is equal to the area of ​​the whole rectangle, minus the area of ​​the small rectangle.

Area of the whole rectangle:

<em>l = 15mm, w = 9mm</em>

<em>A₁ = (15)(9) = 135 mm²</em>

Area of the small rectangle:

<em>l = 7mm, w = 4mm</em>

<em>A₂ = (7)(4) = 28 mm²</em>

<em></em>

Area of the shaded region:

<em>A = A₁ - A₂</em>

<em>A = 135 - 28 = 107 mm²</em>

Answer:

107mm²

Step-by-step explanation:

The whole square:

9mm × 15mm = 135mm²

The white area:

7mm × 4mm = 28mm²

Now subtract the white area from the whole square:

135mm² - 28mm² = 107mm²

Shaded Area: 107mm²

Triangle ABC is an obtuse triangle with the obtuse angle at vertex B. Angle A must be
kvv77 [185]
Answer:

Angle A must be acute.

Explanation:

Both angle A and C must be acute. The sum of the angles in a triangle is 180°.

An obtuse angle is more than 90°, so the sum of the remaining 2 angles has to be less than 90°.

Note that it is impossible to have:

<span>2 right angles in a triangle, because <span>90°+90°=180</span>° and the third angle still needs to be added.1 obtuse and 1 right angle in a triangle, their sum is more than 180°2 obtuse angles in a triangle, their sum is more than 180°</span>

It is possible to have an obtuse-angled isosceles triangle, but the vertex angle must be obtuse and the equal base angles will be acute.

The sum of two confescutive integers is at least 46. What is the least possibly pair of integers?
dezoksy [38]
An integer is a whole number. Sum means to add and since they are consecutive, there is only a difference of 1 between them.

1) 21 + 23: not consecutive
2) 23+24= 47: has to be at least 46
3) 22+23= 45: has to be at least 46
4) 24+25= 49: has to be at least 46

So we have two possibilities: either #2 or #4. Find least possible pair of integers.

x= first integer
x+1= second integer

x + (x+1) >= 46
2x + 1 >=46
2x>=45
x>=22.5

Answer:
The first integer has to be greater than or equal to 22.5. Since integers are whole numbers, round up to the next whole number. The least possible integers are #2) 23 and 24.

Hope this helps! :)
