How the WVGSA reports it

West Virginia’s General Summative Assessment is a state assessment aligned to the West Virginia College- and Career-Readiness Standards rather than a separate national assessment framework. The math blueprint follows CCSS-style grade-band domains and clusters, but the standards are the state’s own West Virginia College- and Career-Readiness Standards.

Blueprint & weighting

WVGSA uses the Independent / state-specific framework (by grade domains structure).

What is the distance from (0,0)(0, 0) to (3,4)(3, 4)?

32+42=9+16=25=5\sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5.

In RST\triangle RST, R\angle R and T\angle T are congruent. The measure of each of these angles is 43.943.9^{\circ}. What is the measure of S\angle S?

The congruent angles total 2×43.9=87.82 \times 43.9^{\circ} = 87.8^{\circ}, so S=18087.8=92.2\angle S = 180^{\circ} - 87.8^{\circ} = 92.2^{\circ}.

The legs of a right triangle are 1212 inches and 3535 inches long. How long is the hypotenuse?

The legs are 1212 and 3535. By the Pythagorean theorem, 122+352=144+1,225=1,36912^{2} + 35^{2} = 144 + 1{,}225 = 1{,}369, so the hypotenuse is 1,369=37\sqrt{1{,}369} = 37.

A right triangle has legs 88 and 1515. What is the hypotenuse?

82+152=64+225=2898^{2} + 15^{2} = 64 + 225 = 289, so the hypotenuse is 289=17.\sqrt{289} = 17\textsf{.}

A wheelchair ramp rises 55 feet over a horizontal distance of 1212 feet. What is the length of the ramp?

The ramp is the hypotenuse of a right triangle with legs 55 and 1212: 52+122=25+144=169=13\sqrt{5^{2} + 12^{2}} = \sqrt{25 + 144} = \sqrt{169} = 13 feet.

A rectangle has length 88 centimeters and area 120120 square centimeters. What is the length of a diagonal of the rectangle, in centimeters?

Area A=wA = \ell w, so 120=8w120 = 8w and w=15w = 15. The diagonal is the hypotenuse of a right triangle with legs 88 and 1515: 82+152=64+225=289=17 cm.\sqrt{8^2 + 15^2} = \sqrt{64 + 225} = \sqrt{289} = 17\text{ cm}\textsf{.}
