Please i need helpp ion get math at all

fiasKO [112]

Answer:

you have to use the Pythagorean theorem. a^2 + b^2= c^2

72^2 + b^2 = 75^2

5184 + b^2 = 5625 (subtract 5184 from both sides)

b^2= 441 (find the square root of each side)

b= 21

0.6(4-2x)=20.5-(3x+10)

solong [7]

The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5

Solution:

Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )

We have to solve the above given equation for x.

Now, take the equation

$\rightarrow 0.6(4-2 x)=20.5-(3 x+10)$

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction

On solving the brackets, we get

$\rightarrow 0.6 \times 4-0.6 \times 2 x=20.5-3 x-10$

Now multiplication is given preference

$\rightarrow 2.4-1.2 x=10.5-3 x$

$\rightarrow 3 x-1.2 x=10.5-2.4$

Now subtraction is done

$\rightarrow 1.8 \mathrm{x}=8.1$

Now division is performed

$\rightarrow x=\frac{8.1}{1.8}=4.5$

Hence, the value of x is 4.5

In △ E F G , △EFG, G E ‾ ≅ F G ‾ GE ≅ FG and m ∠ F = 5 5 ∘ . m∠F=55 ∘ . Find m ∠ E . m∠E.

Bingel [31]

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

$\overline{GE}$ ≈ $\overline{FG}$

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.
