I need help on this.
liraira [26]

If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal.  This proportion would look like:

\frac{2x+1}{3x}=\frac{10}{14}

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).


Now, cross multiply and solve for x:

28x+14=30x

<em>*Subtract 28x from both sides to isolate the variable*</em>

14=2x

<em>*Divide both sides by 2*</em>

7=x


Hope this helps!!

Triangle ABC has side lengths: AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm ΔABC ≅ ΔHJK What is the length of side HJ?
Licemer1 [7]
For this you'll want to draw out Triangle ABC and label it as the problem gives you.

Draw a similar triangle to the first one you drew and label it the exact same way as "ABC" and then match the measurement "AB" to "HJ".

Hope this helps.

Quadrilateral ABCD ​ is inscribed in this circle.
miskamm [114]

The measure of angle A is 65°

Explanation:

Given that ABCD is a quadrilateral inscribed in a circle.

The measure of angle A is \angle A=(2x+1)^{\circ}

The measure of angle B is \angle B=148^{\circ}

The measure of angle D is \angle D=x^{\circ}

We need to determine the measure of angle A.

Since, we know that the angles B and D are opposite angles and the opposite angles of a quadrilateral add up to 180°

Thus, we have,

\angle B+\angle D=180^{\circ}

Substituting the values, we have,

148^{\circ}+x=180^{\circ}

          x=32^{\circ}

Thus, the value of x is 32°

Substituting the value of x in the measure of angle A, we get,

\angle A=(2x+1)^{\circ}

\angle A=(2(32)+1)^{\circ}

\angle A=(64+1)^{\circ}

\angle A=65^{\circ}

Thus, the measure of angle A is 65°
