Answer:

the answer is 60°

Step-by-step explanation:

if you set 60=4x , then x = 15. (15•10)-45 = 105, meaning the third angle of the triangle is 75. then you multiply 15•4 = 60, and then the other angle would be 15•3 = 45. then 75+60+45 = 180

A rhombus has its diagonals 7cm and 6 cm whats its area
ipn [44]

\large\frak{ Given :}

  • Diagonal of a rhombus = 7 cm and 6 cm

\large\frak{Find:}

  • Area of a rhombus

\large\frak{Explanation :}

\small\tt Area = \frac{1}{2}× d¹ × d²

<u>Where,</u>

  • d¹ = length of diagonal 1
  • d² = length of diagonal 2

\implies \small\tt{ \frac{1}{2}  \times 7 \times 6}

\implies\small\tt{ \frac{1}{2} \times 42 }

\implies \small\tt{Area = 21  {cm}^{2}  }

When you receive a loan to make a purchase, you often must make a down payment in cash. The amount of the loan is the purchase c
emmainna [20.7K]
Summarizing the problem, there are three terms that you have to deal with: purchasing cost, down payment and loan. So, you would expect that the answer would contain these quantities. Among them, the unknown is the purchasing cost, therefore, we denote this as x. 

<span>Based on the statement, "The amount of the loan is the purchase cost minus the down payment", we can formulate an equation for this. 

Amount of Loan = x - Down payment

This will be our working equation. Moving on, the down payment was mentioned to be equal to </span>$1500. The lean received is equal to <span>$2600. Substituting these values to the working equation, we can now determine the value of x.

2600 = x - 1500

Solving for x by transposing it to one side,

x = 2600-1500
x = $1,100

Therefore, the purchasing cost of the car is $1,100.</span>

Determine the value of a so that A = 2i+aj+k and B = 4i-2j-2k are perpendicular​
Digiron [165]
In order to make them perpendicular, their dot product must result in zero. so:

4 \times 2 - 2a - 2 \times 1 = 0

2a = 8 - 2 = 6

a = 3

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a
rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 =  45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>
