From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"

y^2 + b^2 = a^2
y^2 + c^2 = x^2

y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2

a^2 - b^2 + c^2 = x^2

Now put in the values given for a,b,c to solve for x

(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x

76 div 4 a)15 b) 8 c) 19 d) 0 Explain

Sunny_sXe [5.5K]

Answer:

C. 19.

Step-by-step explanation:

Let's find the answer.

Step 1: divide the first number of 76, which is 7, by 4 and find the integer part.

7/4=1.75, so the integer part is 1.

Step 2: subtract from 7 the (integer part times 4)

7-(1*4)=3

Step 3: put toether the result (3) and the second number of 76, which is 6, so the result is 36.

Step 4: find how many times we need to add 4s to reach 36, so:

4+4+4+4+4+4+4+4+4=36 which means that:

36/4=9

Step 5: put together the two resulted numbers calculated in step 1, which is 1, and step 4, which is 9:

1 and 9 giving 19, so the answer is:

76/4=19.

In conclusion the answer is C. 19.

1. Two triangles have the following congruence statement: ACGI = AMPR Name all 6 pairs of corresponding congruent parts. 1.

rodikova [14]

Answer:

$\angle C \cong \angle M$

$\angle G \cong \angle P$

$\angle I \cong \angle R$

$\overline{CG} \cong \overline{MP}$

$\overline{GI} \cong \overline{PR}$

$\overline{CI} \cong \overline{MR}$

Step-by-step explanation:

Given the congruence statement ∆CGI $\cong$ ∆MPR, it follows that the corresponding sides of both ∆s are equal, as well as the corresponding vertices or angles. It implies that ∆CGI and ∆MPR are of the same shape and size.

✅Thus, the 6 pairs of the corresponding congruent parts of ∆CGI and ∆MPR are:

$\angle C \cong \angle M$

$\angle G \cong \angle P$

$\angle I \cong \angle R$

$\overline{CG} \cong \overline{MP}$

$\overline{GI} \cong \overline{PR}$

$\overline{CI} \cong \overline{MR}$

1/2x+2 = x/2x^2+8 Show work plz

Igoryamba

Answer:

x=24

Step-by-step explanation:

1/2x+2 = 1/2x^2+8

1/2x^2=1/4x

1/2x+2=1/4x+8

1/2x -1/4x =0.25x

0.25x+2=8

8-2=6

0.25x=6

0.25/6 = 24

x=24

Are the numbers (2,3)(1,5)(2,7) a function ?

Arturiano [62]

Firstly they are not numbers, they are ordered pairs or points with a form $(x,f(x))$ yes they probably lie on a function graph but that would be rather impossible to find out. The function may be linear, exponential, logarithmic etc. we can't tell. All we can tell is that if these ordered pairs $P_{1,2,3}$ lie on a function graph $P_{1,2,3}\in G_f$ where $G_f=\{(x,f(x)):\forall x\in D_f\wedge f(x)\in T_f\}$ where D is definition set of function defined x's and T a transformation set of f(x)'s for this function. So yes they may lie on some lambda function but they themselves are nothing but an ordered pairs with no meaningful connection.

Hope this helps.
